I Can't Change My Phone Number on Yalla Ludo

I am a Yalla Ludo user and I need help adding a new mobile number to my account. My in‑game name is ZAHID and my user ID is 5000717***. The old phone number linked to my account is no longer active, so I cannot use it anymore. I kindly request that you remove the old phone number from my Yalla Ludo account and add my new mobile number: 966 579298***. I want to keep using my account safely and receive all verification codes and notifications on this new number. Please update my account information as soon as possible and inform me when the change has been completed.
