WotLK Help, I was banned or my account was stolen!

[Undysss]

The last time I visited was about 3 months ago. I passed two-factor authorization, played a little and logged out of my account. After a while, I can't log in to the game, I write an incorrect pin from my account and from the forum. Trying to restore the pincode, I was sent an email that is not coming! Please ask for help with data recovery. I have all the screenshots of the characters I played on, I can list the names, the number of rating accounts taken, and of course account information, login, pincode, gmail. Login of my main Undyss account / Please help! [email protected]
