How to complain to the RBI Ombudsman: bank complaint and CMS checklist

If a complaint against your bank remains unresolved, the next step may be the RBI Complaint Management System (CMS). Start by complaining to the bank itself and saving its acknowledgement. CMS is an escalation route for eligible complaints against covered regulated entities; it is not a substitute for first identifying the service failure and asking the institution to correct it.
Start with a written complaint to the institution
Use the bank's official grievance channel. Describe the account or service involved, the disputed event, its date and the correction requested. Include only the account identifiers needed for the secure form. Keep the complaint reference, the exact submission and evidence of delivery together. If a branch conversation was important, record its date and follow up in writing so the substance is clear.
A useful opening is specific: an unexplained charge was debited on a stated date, you requested its basis, and the response did not answer that question. That is easier to assess than a general statement that customer service is poor. Explain the financial effect separately from the inconvenience and show how you calculated any amount claimed.
Check the current eligibility and filing window
The RBI's current FAQs describe the 2026 scheme. They provide for escalation after an unsatisfactory response or after the applicable response period has expired without a reply. The ordinary period is 30 days, but a longer RBI, NPCI or card-network period can apply. The current filing window is 90 days from the relevant period's expiry or the last communication from the institution, whichever is later.
Check the scheme itself for coverage, exclusions and any exceptional treatment of delay. Do not copy a deadline from an older article describing the 2021 scheme. If another proceeding already concerns the same dispute, disclose it and examine maintainability before filing. A complaint acknowledgement is not a finding that the matter is eligible.
Build a compact complaint packet
- Your first complaint and its acknowledgement.
- The institution's replies, including the most recent communication.
- Relevant statement entries, transaction references, messages and service terms.
- A short timeline separating the original event from subsequent follow-up.
- A precise remedy and a calculation of the amount, if any, requested.
Label attachments by purpose rather than uploading an entire unsorted account history. For example, use separate files for the disputed entry, the first complaint and the bank's response. Keep an unmodified original of every record. Where a document contains unrelated sensitive information, check the official submission requirements before providing it.
Submit through the official CMS route
Open cms.rbi.org.in directly. Check the institution's identity, your contact details and the complaint category. Explain what remains unresolved after the bank's response; do not simply attach correspondence without a narrative. Save the completed submission and complaint reference. Filing through the Ombudsman mechanism is free; a paid intermediary cannot guarantee an award.
Follow up using the same record
Keep a log with four columns: date, action, reference and next response expected. If you receive a request for clarification, answer that request and identify the relevant attachment. If the bank later offers a correction, compare it with the original complaint before accepting a settlement. Keep any acceptance, closure communication or order for future reference.
This route does not guarantee repayment or compensation. A fraudulent transfer may also need urgent reporting to your bank and the cybercrime system: see our financial-fraud reporting guide. For a failed rather than fraudulent payment, the failed UPI payment checklist helps organise the different issue.
