I approved a UPI collect request by mistake — can I reverse it?

Contact your bank's fraud helpline immediately with the UPI transaction reference (UTR). UPI transfers are usually instant and reversal depends on timing, recipient bank cooperation, and whether funds are still in the scammer's account — success is not guaranteed. Acting within minutes improves chances. Also file on cybercrime.gov.in. Future prevention: never approve unexpected collect requests, even for ₹1.
