I tried to login to Diablo 3 and get a message stating 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 authenticator code is wrong. Trying to login to Diablo 3 gives error message wrong password.

Mobile Authenticator

Like fbueckert said in their comment, if it's a Mobile Authenticator, try closing and re-opening it.

Another possibility is that your Serial has got out of Sync. Which this means you will most definitely have to get in contact with customer support.

Suggestion

Since you can't log into your account, I'd recommend giving them a call. I've had both good and bad experiences while calling
