How to register complaint for UPI transaction?

To register a complaint for a UPI transaction, you should follow the structured redressal mechanism:

• Start by using your app's "Help" or "Support" section, select the problematic transaction, and raise a concern directly with the provider.
• If your issue is not resolved by the app, escalate the complaint by contacting your bank's customer service.
• As a final step, you can file a complaint on the National Payments Corporation of India (NPCI) dispute redressal portal or call their official number, 1800-120-1740.
