To refund money from a BHIM UPI transaction, you should first report the issue within the app by selecting the specific transaction and choosing Raise Concern or Report Issue. For failed transactions where money was deducted, reversals typically occur within T+2 working days. For incorrect transfers:
- Contact your bank immediately with the 12-digit transaction ID to file a chargeback.
- Reach out to the unintended recipient to request a return of funds.
- Submit a grievance on the official NPCI website under the UPI Dispute Redressal Mechanism if the bank does not resolve the issue.
