Account needs 4-digit code when i log.

Hello, I am an old warmane player, i play here since it was named Molten. (as far as i remember i play here since 2011)
I own 3 accounts. (I can prove that all these accounts are and were always mine.)
I was half year trying to finish my university so i was not so active.

Now, that i started playing again, i cannot have access to one of my accounts.
In my other two accounts i can log with no problem.
It says, it requires a 4-digit code that was sent to the e-mail of the acc.
I remember the e-mail i had put (which i had created ONLY for the wow account) (- you could accept hotmail adress back then.)
However since then i didnt log into this e-mail, it is an old and inactive address.
It says that a code has been sent to my e-mail.

Please , with all the respect some modeterator contact me because i sent e-mail to [email protected] and got no answer.
Help me out !!! I miss my priest :(

you may open a ticket on website if you are premium with one of your other account

I'm not. Just a loyal regular player .

Same here... I also own 2 accounts, with the only difference between account names and passwords being a single digit. I never had any problems logging in, until now. I can log on one account, and I can't log on to the 2nd one.
ANY help would be welcome, as some nicely geared MoP chars are there, that I wouldn't want to lose. :)

Send an email to [email protected] with proof.

exactly ! 1 digit difference.
It would be nice if some modeterator see this post.
Also [email protected] doesn't respond.
