How do I find the UPI complaint number

To check the status of an NPCI UPI complaint, visit the NPCI register a complaint webpage. Look for the option to check the complaint status, which usually requires entering the product type, bank details, and the CRN (Complaint Registration Number) or a complaint reference number. Alternatively, if you raised the complaint through a service provider like Paytm, use their in-app support feature to view updates on your resolution status.
