WotLK Account Hacked and characters either deleted or traded to another account ?

[buttermilk]

My characters are missing from my account. I logged in and they are gone. How can I get help restoring them?

[skullatbash]

when did you play last time with them?

Anyway they can be restored here ( if deleted in tha past 30 days): https://www.warmane.com/account > services > Character restoration
