Guy I need some help regarding my account in diablo 3,
one years ago, I have created my battle.net account with only remember my password and log in name, other than that I have no idea what information I have given much during the creation of this account.

So recently I have been hacked so when I required to login to "rollback" my account in game, I realised that my account being locked due to suspicious activities (I seldom log in this email address as it was my secondary email address, offcause I still manage to log in) as I was forget all my other information during my creation of this account.

So actually I have no idea how to reset my password, manage my account other information and using authenticator.

I need some help here, thanks for the advise and useful link here.
