I finally got my bnet name change! When I created my first bnet account, I was 19 or whatever and used a fake name because it was the first time I had ever really put my information online and was nervous as hell (lol). Unfortunately for me, the fake name is actually a real name, not like Mickey Mouse or stuff like that. While this wasn't really a huge deal to have a different name, I was nervous that if I would ever lose access to the account, I would have no way to get it back. As this is my main account (since 2008), all the expansions, toons, gold, etc I couldn't just go create a new bnet.
I first ticketed 11 mmonths ago explaining my quandry. I received the copy/paste response of they need legal name change papers, etc. Well I didn't have any of that cause it was a fake name so I was shot down. I tested my luck by making a ticket about every month, always being respectful. Finally yesterday I received a response hinting that if I could provide documents to undoubtedly prove I was the owner of the account, there was a small chance the GM could do something about it.
BA BOOM. I uploaded 20 pages of account purchases, physical CD keys of what I had, my paypal statements with account purchases, and emails from 2008-2016.
I got the response last night claiming that my name had been changed!
So so so so so excited. Again not a huge, huge deal. It was my fault to begin with. But I feel so much more confortable playing when my real name is actually on the account

tl:dr - was able to change my name on bnet account after a long battle
