I tried to login to diablo 3 it says wrong password.

I reset my password. But when I enter the password I remember, it says that I can't use the same password with existing password.

Then I change password to a different password anyway.

I tried to login again and the authenticator keeps giving the wrong number.

So I can't login to the battle net and then I can't ask support because only those who login can submit ticket.

In short, trying to login to my account gives error message aunthenticator code is wrong. Trying to login to diablo 3 gives error message wrong password.
