[ANSWERED]Lost account

I'm coming back to WoW, but when I tried to log in with my second account, it says that the password has expired, and a new one is sent to my mail. My problem is I don't remember the email account, and can't retrieve my password. I can give the account name, or any information that you ask . So, please help me get my account back .

I sent an email to [email protected] waiting for an answer for too long so how long does it take to get a respond ?

You must be patient but answer should be no late than few days.
