Please get in touch with our customer service team as soon as possible. If you are still able to login to your G-Coin wallet, we will help you update your email address. If you are unable to login, you may be asked to undergo a verification process with an independent third party to confirm your identity. In this case, certification by the third party is required to restore access, as we do not retain access to your account credentials, and it is impossible for us to restore your account without third-party verification and signature for such action.
