It is not possible to cancel or reverse a successful UPI transaction once you have entered your UPI PIN, as the funds are transferred instantly in real time. If you have sent money to the wrong recipient, you should immediately:
- Report the issue through the support or help section of your UPI application.
- Contact your bank's customer care to request a reversal or formal intervention.
- File a formal complaint on the NPCI Dispute Redressal Mechanism portal if the issue remains unresolved after contacting your bank.
