If you have already raised a support ticket regarding a failed transaction refund on Paytm (following the steps in your transaction history) and the amount is still not credited:

• Reply and Escalate: Do NOT raise a new ticket. The most effective next action is to reply directly to your existing open ticket. State clearly that the refund reversal has not occurred since the complaint was logged.
• Review Agent Notes: Check the ticket history for any notes or requests from the support agent. If they have requested specific bank details or documentation, provide it immediately.
• Monitor: Continue to monitor the ticket status and your original payment source for the credited amount. The internal escalation usually leads to faster tracing of the reversed funds.
