Three decades. That is how long Master Capital Services Ltd., the broker, has been operating in Indian financial markets. A SEBI registration dating back to October 1994.
On the surface, it reads like the profile of a dependable, well-established broker. Yet Master Capital complaints tell a different story.
One where an authorised person allegedly ran unauthorised trades in a client’s account for years without her knowledge. Where users describe the app as bug-ridden, the charges as excessive, and the helpdesk as dismissive.
Thirty years of operation do not guarantee thirty years of trustworthy conduct. This blog lays out every documented concern, so you can decide with your eyes open.
Master Capital Complaints Overview
According to Mastertrust’s official website, Master Capital Services Ltd. holds SEBI Registration No. INZ000210539 is a member of NSE and BSE.
Many investors wonder: Is SEBI registered broker safe?
While registration ensures that a firm is under the regulator’s eye, it is not a blanket guarantee of ethical conduct.
As of 2026, SEBI has tightened regulations, especially around the strict segregation of client funds. Still, past complaints show that even with rules in place, gaps can exist in how things are handled at the ground level.
This regulatory backing is supported by a wider corporate presence. The Mastertrust group isn’t limited to broking; it also runs Master Portfolio Services Ltd as a registered portfolio manager, along with its listed entity, Master Trust Ltd.
Mastertrust offers its retail clients a mobile and web-based trading platform for equity, derivatives, currency, and commodity segments. It is also the primary source of master capital complaints from everyday users.
The pattern is consistent: charts that display incorrect data, a bloated interface that slows down order placement, and bugs that have remained unaddressed despite user reports.
For investors trading intraday or options, a laggy, inaccurate platform is not an inconvenience; it is a direct financial liability.
Types of Master Capital Complaints Clients File
Master Capital complaints are not limited to one type of failure. They cut across technology, operations, and conduct.
This analysis of Master Capital complaints is based on exchange data, arbitration records, and verified user experiences.
Beyond what investors report informally, the exchange formally handles structured grievances.
| Type | Description of Complaint Type | Count |
| Type I | Non-receipt / delay in payment | 12 |
| Type II | Non-receipt / delay in securities | 2 |
| Type III | Non-receipt of documents | 4 |
| Type IV | Unauthorised trades/misappropriation | 32 |
| Type V | Service related | 49 |
| Type VI | Closing out / squaring up | 1 |
| Type IX | Others | 28 |
The most common issue is service-related complaints, indicating frequent problems with order execution, platform performance, and customer support.
This suggests that users consistently face difficulties in day-to-day trading operations, affecting both efficiency and trust.
Master Capital Exchange Complaint Data
Here is the year-by-year picture of how many clients formally escalated disputes with Master Capital Services to the exchange level:
| Financial Year | Active Clients | Complaints Filed | Resolved | Complaint % | Resolution % | Arbitration Cases |
| 2025–26 | 59,194 | 22 | 21 | 0.037% | 95.45% | 0 |
| 2024–25 | 65,258 | 66 | 66 | 0.100% | 100% | 0 |
| 2023–24 | 60,064 | 21 | 18 | 0.030% | 100% | 1 |
| 2022–23 | 60,064 | 30 | 26 | 0.040% | 100% | 2 |
A few data points worth building your analysis around:
- Complaint spike in 2024–25, then partial drop. Complaints tripled from 21 to 66 in a single year, then fell back to 22 in 2025–26. That’s not a clean recovery story; it raises the question of what caused the 2024–25 surge.
- First unresolved complaint in 4 years. After three consecutive years of 100% resolution, 2025–26 shows 1 complaint still open (21 resolved out of 22). A small number, but the streak is broken.
- Two arbitration cases in 2022–23. The highest in the dataset signals that at least two investors escalated to formal legal proceedings that year.
- The client base is shrinking. Down from 65,258 to 59,194, a drop of over 9% in one year, while complaints haven’t reduced proportionately.
Master Capital Arbitration Case
This is one of the most significant and investor-relevant Master Capital complaint cases on record.
As per NSE Arbitration Matter No. NSLBEN/0017884/20-21/ISC/IGRP/ARB, the case was decided by Sole Arbitrator Mrs Radha A K in Bengaluru on July 7, 2023.
Case Overview: Unauthorised Trading Allegation
A female investor from Bangalore alleged that trades were executed in her Mastertrust account (Client Code: 6HVT04) without her consent.
The investor claimed that all trades in her account were carried out without her knowledge or approval.
According to her, the trades were executed either by the authorised person or through an automated system.
When she attempted to resolve the issue, she found that the authorised person’s office was no longer operational. This raised serious concerns about oversight and client protection.
Master Capital submitted telephone recordings in CD format. However, when transcripts were reviewed, there was no evidence showing that the investor had given prior consent for any trade.
Final Verdict and Penalty
The tribunal concluded that trades were executed in the investor’s account without her consent.
As a result, the earlier IGRC order was set aside. Master Capital was directed to pay ₹4,43,252 as compensation for losses caused by unauthorised trading.
What Every Investor Must Take Away from This Case
- A broker’s authorised person is legally the broker’s responsibility. If that individual operates fraudulently, the broker cannot simply deny the connection and walk away. The tribunal rejected that defence entirely.
- SEBI’s 2018 circular mandates that brokers maintain evidence of client order placement, voice recordings, emails, internet logs. If a broker cannot produce these when challenged, the presumption moves against them.
- Login access is not cosmetic. If you cannot log into your own trading account, that is not a technical glitch, it is a red flag that someone else may be controlling it. Report it immediately and in writing.
- IGRC proceedings are not the end of the road. This investor returned after an unsatisfactory IGRC outcome and won at arbitration. Persistence through the system pays off when you have a genuine case.
- Document everything from day one. Account activation confirmations, welcome letters, any communication about login credentials, keep copies of all of it.
Master Capital User Reviews
The Google Play reviews for Mastertrust’s trading application reveal a ground-level picture that no marketing material would acknowledge.
Here is what investors are genuinely saying:
1. Helpdesk That Listens to Nothing
A user gave a 1-star rating in May 2025 and described being unable to update or change bank account details through the app, even after completing a re-KYC process.
The reviewer noted that the helpdesk showed zero interest in understanding or resolving the problem, and described the attitude as dismissive and disrespectful.
For any investor, the inability to update bank account details is not a minor inconvenience.
When that failure is compounded by a support team that refuses to engage, the investor is effectively trapped.
2. High Brokerage Charges
A user posted a 1-star review in March 2025, with 6 users marking it helpful, describing both the company and the app as “hopeless.”
The reviewer flagged that even the most basic tasks on the platform were difficult to complete.
Furthermore, they pointed out that Mastertrust imposes very high charges for services that other brokers provide at a fraction of the cost.
3. Bug-Filled App With Charts That Show the Wrong Prices
A user gave a 1-star rating in August 2025 and described the app as full of bugs, prone to hanging during use, and cluttered with useless pages that slow down the time it takes to place an order.
Most critically, the charts were flagged as showing incorrect data, different from what is displayed on TradingView for the same instruments at the same time.
Wrong chart data does not just create confusion; it leads directly to wrong entries, wrong exits, and avoidable losses.
When To Take Action Against A Broker?
There is a point beyond which waiting for a broker to fix things stops being reasonable and starts being expensive.
For master capital clients, that threshold includes:
- Account Access You Never Had: If you opened an account and were never able to log in properly, do not wait. This is precisely the scenario in the NSE arbitration case above documents.
- Trades in Your Account You Did Not Place: Zero tolerance applies here. Screenshot your positions, download your account statement, and file a written complaint with the broker and the Cyber Cell simultaneously.
- Bank Details That Cannot Be Updated: If the app refuses to allow basic account management and the helpdesk provides no solution, escalate to the exchange in writing.
- Chart Data That Diverges from Market Reality: Document the discrepancy with timestamped screenshots of both your broker’s app and an independent price source.
- Charges That Were Never Disclosed: Compare your contract notes against your account opening documents. If the charges applied do not match what was agreed, calculate the cumulative difference and escalate.
- Support That Has Been Unresponsive for More Than Three Days: Stop calling. Switch entirely to email. Create a written trail. Then file at the exchange level.
Where to Complain About Stock Broker in India?
Do not skip steps. Each stage creates a documented record and progressively increases the pressure on the broker.
Here is the step-by-step process to register a complaint against a stock broker:
Step 1: Formal Written Complaint to Broker
According to Mastertrust’s official investor grievance page, clients can raise complaints via the official grievance mechanism.
Every detail goes in writing, client ID, dates, specific transactions, the exact nature of the issue, and all supporting documents.
No phone calls as the primary record.
Step 2: File a Complaint in SCORES
If the broker fails to resolve your issue within the prescribed timeframe (typically 30 days), you can escalate the matter by filing a complaint on the SEBI SCORES portal.
This is the official platform backed by the regulator, where SEBI online complaint status is tracked, and resolution timelines are monitored. Registered intermediaries are obligated to respond within specified deadlines.
You can also track the status of your complaint directly through the portal dashboard.
Step 3: Report a Complaint in SMART ODR
If you are not satisfied with the outcome on SCORES, you can take the next step by raising your case on the SMART ODR platform.
This system facilitates structured online dispute resolution, including mediation between investors and intermediaries to reach a fair outcome.
Step 4: Arbitration in Stock Market
If the dispute remains unresolved, you can initiate arbitration through recognised stock exchanges such as the National Stock Exchange or BSE Limited.
Arbitration is a formal, legally binding process where an independent arbitrator evaluates the case and issues an enforceable decision, offering a final avenue for resolving investor-broker disputes.
Need Help?
Dealing with a master capital complaint that keeps hitting dead ends? Can’t get the helpdesk to engage? Unsure how to frame your evidence for the exchange?
The system works, but navigating it alone, without knowing exactly which documents matter or which escalation path to take, is unnecessarily hard.
Moreover, brokers are aware that most investors will eventually abandon even valid claims.

We will help you build your case, understand your rights, and take the right action at the right time.
Conclusion
Master Capital Services Ltd. is a three-decade-old, SEBI-registered broker with memberships across every major Indian exchange. The SEBI registration is genuine.
None of that changes what the documented record shows. Master capital complaints spiked by 214% in a single year. The client base is simultaneously shrinking.
An NSE arbitration tribunal overturned an earlier decision and ordered the broker to pay ₹4,43,252 to an investor whose account was allegedly traded without her knowledge for years.
App users consistently report bugs, incorrect chart data, and a support team that does not engage meaningfully with problems.
Thirty years in the market is worth something. But it does not override the obligation to maintain client accounts securely, respond to complaints promptly, and keep platforms accurate during live trading hours.
Verify your account activity regularly. Screenshot anything unusual. And if something feels wrong, act on day one, not day thirty.
