FamPay Old Phone Number Change

I have been facing a problem with my FamPay account since 20/02/2025 because I lost access to my old phone number that is registered on the account. Due to this, I am unable to change my phone number from my side and I am worried about the security and future access to my account. I request you to close or remove my old registered mobile number from my FamPay account and update it with my new mobile number, which is linked to my Aadhaar card. I am ready to provide any necessary identity or Aadhaar-related verification if required so that you can safely update my account details. I kindly ask you to resolve this issue as soon as possible and confirm once my FamPay account is updated with my new Aadhaar-linked mobile number.
