Gmail Account Hacked; Battle.net Account Created

[Verum]

So I logged on gmail yesterday and they informed me that my account had been accessed via China. Ok, email account password changed and anything else that seems important. Next thing I noticed this morning that a Battle.net account was created with my email address. Given that I no longer play warcraft and never will I went ahead and verified the battle.net account to see where this goes. Unfortunately I can't use the automated system to get the password to the account because I don't know the surname of the person that created the account, only his first, Zhang (Lol). What is up with this shit I haven't played WoW in over 2 years but must have clicked on something that made them think I am. Thoughts?

P.S. my wow account wasn't even connected to the email address.
