Unable to Access FamPay Account After Changing My Mobile Number

I was previously using the Jio number 9623273***, which I had linked to my Fampay account. Now my number has changed and I am using the new number 7709796***, but I am unable to log in to my existing Fampay account because it is still connected to my old Jio number. Because of this, I cannot access my Fampay account and it is causing me problems in using the service. I want my old Fampay account, which is linked to 9623273***, to be updated so that I can log in and use it with my new number 7709796***. I request that this issue be checked and that my number for Fampay access be changed so that I can continue using my account without any problem.
