WePlay Phone Number Already Bound to Another Account Error

I have been experiencing a problem with the WePlay application on my Android phone for the last three weeks. When I try to bind my phone number to my account, the app shows the error message “This number has already been bound to another account” for my number, and it does not allow me to complete the binding process. Because of this issue, I am unable to link my phone number to my own WePlay account and I am worried that I may lose access to my data if I ever uninstall the app or log out of the game. I have already submitted a complaint to WePlay support about this problem, but I have not received any response so far. I request that my phone number be unbound from any other account it might be linked to by mistake and be properly bound to my current WePlay account, and that I receive a clear response regarding the resolution of this issue.
