How do I file a UPI complaint online?

A UPI complaint can be logged through the official channels of your UPI service provider, such as the bank's app or payment app. Most UPI apps have a built-in support feature to report issues directly. You can also raise a complaint via the National Payments Corporation of India (NPCI) portal or the official BHIM "Get In Touch" page by filling out the form with details like the transaction ID, UPI ID, and bank information.
