Hello! In forums of other games I have read that there is a way of hacking that is to impersonate the identity, that is, steal your account without having given your password to anyone.
Anyway, even if you had given your account in good faith to someone, I support you 100%. I have always said, a thief is a thief, it does not matter if you were careless with your account or not.
This is what TS says that if you have given your password, then they don´t take responsibility, it’s just a way to wash hands. Whistle and look the other way. You have a thief at home and you do nothing.
