FamPay Device Access Paused for Multiple Sign Ups on Oppo A3 Pro

For about one year I have been unable to use my FamPay account on my Android phone (Oppo A3 Pro) because my device access has been paused due to “multiple sign up”. When I open the app, I receive a “Device access paused” message stating that, due to security policy and multiple registrations or logins, my device has been blocked. My current phone number linked to this device is 8088935***. I no longer remember the details of the first SIM I used with FamPay, so I am not able to complete the standard verification process or recover my previous access by myself. I have already tried contacting support through the in‑app option, but I have still not received any effective solution or clear guidance. I kindly request that you review my case, remove the device access restriction related to the “multiple sign up” flag on my Oppo A3 Pro, and allow me either to sign up again or to log in using my current number so that I can start using FamPay normally again. I urgently request that my device and account be unblocked as soon as possible so that I can resume using FamPay without further delay.
