If you can sufficiently identify that you are the registered user on the account, which will likely require sending in a valid ID, verification of the CD keys on the account as well as a number of internal verifications, our Billing and Account Services team may be able to help.
Give them a call, they'll let you know what is needed and if they are in a position to assist. :)
You can call 1 (800) 592 5499 (1-800-59-BLIZZARD) 7AM-8PM (PST/PDT) for live representation.
Australian users should please call 1-800-041-378 if the standard 800 line does not work.
Good luck!
