My credit card statement shows a different total than the sum of my individual purchases. I contacted customer service, and they acknowledged a mistake. I have proof of their error and want to file a complaint. What can I do?

You can file a formal complaint with the bank or credit card issuer, outlining the discrepancy and providing proof of their error. The Reserve Bank of India’s guidelines require banks to investigate and resolve complaints within a specific timeframe. You can also escalate the issue to the Banking Ombudsman if your complaint remains unresolved.
