FamPay Account Recovery Without Access to Old Phone Number

I am having a problem accessing my Fampay account because my old phone number is no longer available and all OTP codes are still being sent to that old number. Since I do not have that SIM card anymore, I cannot log in and cannot complete the “Change phone number” steps shown in the app. I would like your support to update my Fampay account to my new phone number and help me recover full access to my account without using OTP sent to the old number. I am ready to verify my identity with any alternative method you require, such as ID verification or selfie verification, so that you can securely confirm that the account belongs to me. I kindly request you to review my case, help me recover my Fampay account and complete the phone number change to my new active number as soon as possible.
