I Cannot Log In My Old Chamet Acount Because My Number Is Inactive

I have been using Chamet on my Android phone and I can no longer log in to my account because the phone number linked to it is no longer active. The last time I was able to successfully access my account with that number was about six days ago. My old registered phone number on Chamet is 0507550***. Since this number is now inactive, I am unable to receive any verification codes or complete the login process. I would like my account phone number to be updated to my new number, 09764743***, so that I can regain access and continue using my account without interruption. I kindly request your support to change the phone number on my Chamet account from 0507550*** to 09764743*** and help me restore access to my account as soon as possible.
