Update My Mobile Number In FamPay

I have been using FamPay on my Android phone and I am currently unable to access my account because my old mobile number’s SIM card has been lost. For about one month I have not been able to log in to my FamPay account, as all verification and OTP messages are linked to the old number that I no longer have. I contacted FamPay customer support about this issue, but I have not received any response so far. Because of this, my account remains inaccessible and I cannot manage my FamPay services. I kindly request that my FamPay-registered mobile number be updated to my new number after completing any necessary verification, so that I can log in to my account again and use the service safely.
