How long does UPI complaint resolution take?

Generally, UPI complaints filed through your app or bank are resolved within 1 to 3 working days. However, some sources suggest resolution can take between 3 and 7 working days, depending on the bank and the nature of the issue. If the complaint remains unresolved, you have the option to escalate it to NPCI, your bank's grievance officer, or the RBI Ombudsman.
