Nostalrius Begins - Quality wow vanilla realm (1.12)

Dear administration, I have a problem with your account. I have often disconnects from the server. It seems to me that someone hacked my account. I would like to change my password, but I do not remember the email address provided during registration. Restore access to it is impossible. The phone number I have on check-in was lost. I only remember a password. I registered the account at the beginning of March. Could you tell me the mail address provided during registration? I hope for your understanding and an early resolution of the situation. I really liked your server and I called friends to play with me. Thank you in advance.
