How to get the SQ

[jacobaau]

Hello honored ppl.

I've been scaming some accounts and finally I found my dream account.

He used the same pass for his mail so its already changed to mine.

But the problem is:

How can I change my Last name so I can move the character to a new account? I dont even know his last name exept it starts with an L.

I would appreciate if you could give me some tips/methods on how to trick blizzard.
