Withdrawal Error With My Chamet MetWallet App

I am having a problem linking my Chamet account to my MetWallet account and therefore I cannot withdraw my earnings. When I try to bind my MetWallet in the Chamet app, I receive an on‑screen warning saying “Attention: A Metwallet account can only be bound with one account.” I started to receive this error last week and since then I have not been able to connect MetWallet to my current Chamet account or withdraw any funds through it. I request that my MetWallet be unbound from any old or unknown account and correctly linked to my current Chamet account, or that you provide a clear solution so that I can connect it and withdraw my money without any further issues.
