You want to get your banned account back eh? Well, Look at this, it might help like it did to my friend.
It dont really matter how you got banned, 3rd pary programes, exploiting, scamming you name it.
This is how it goes:
Wait like 1-2 weeks after your account got banned and you got your e-mail from Blizzard containing the information about your account getting banned.
When you have waited, Call blizzard and say that you have been on vacation for 1 month and you havent played your account while you were on vacation.
Say that you have never shared your account info to no one else than you, and your account probably got hacked while you were in bahamas having fun.
If they dont listen to you, call them back and tell them that you called them before and dident get your account opened.
You can twist the story too, just say you were on vacation or something and you havent played for some weeks.
Keep doing this till you get it back.
This worked on EU gms.
Enjoy your un-banned account.
