Strange password change emails

Last night i got hacked and there was nothing i could do about it, since the hacker spammed the password request system for my account, thus it was disabled when i actually tried to get my password back. Anyways, this morning i called up Blizzard, proved that i was the original owner of the account, and my password was reset for me.

After the password reset by a blizzard employee, i received an email with something like:

"After a recent review, Blizzard has reset your password. Ur new password is #$#%@#%"<< random numbers and letters.

When i change my password through the account management page, i get an email saying:

"Your password has been changed over account management, if you did not authorize this change do a password recovery"

When I do a password recovery, i first get an email asking me to confirm it. I click the link and it takes me to another form, i fill in my password/acc name, and i get an email:

"Your password has been changed over password recovery, if you did not authorize contact blizzard"

Now here's the weird email i got, which i have no idea how or why i got:

"A request for a new password for your World of Warcraft Account has been received. Your new temporary password is: #$#$%#$%$# " <<random numbers and letters.

Where the hell is this password change from? The only thing i can think of is that i emailed customer support about retrieving my lost items. They may have reset my password. But i got a separate email saying "We do not handle item retrievals, we will forward your email to the appropriate staff".
