How do I complain about the wrong UPI transfer?

If you transfer money to the wrong UPI address, immediately contact the recipient to request a refund. If that fails, reach out to your bank or the UPI payment app's customer support to report the erroneous transaction and raise a complaint. Gather details like your UPI ID, transaction ID, amount, and time. If the issue remains unresolved, you can file a complaint with the National Payments Corporation of India (NPCI) or the Banking Ombudsman.
