A gamer has been asking for help for a week.

I'm a player who came to China. I've sent letters to your company many times and kept me waiting. I admit that my mistake bound the mailbox to a non-existent mailbox, but I can provide all the account information, that is, this account. Now I can only post on the forum, but I can't log in to the game, because I need to send a cancellation code to an existing mailbox to let me log in. God, I'm going crazy. Why can't you help me solve it? The message is the same every time.
