So my friend gave me a world of warcraft account about a year ago so I could rez it for myself and get the mount and I never did anything with it after that. Yesterday, I had this random urge to get the account back(I have no idea why lol, and I spent about an hour trying to do so). The account isn't under my name and I don't remember the email that the account had on it, BUT, I did have the security answer, the CD key, and the name on the account. I'm not a very bright person, so I called blizzard and told them the account was given to me by my uncle(i have no idea why I didn't just say it was mine, don't ask.) Since the account wasn't under my name, and I didn't know the email registered to the account, they couldn't do anything for me.
A little while later, I realized I had the CD key and security answer so I called back and told them the same thing but this time I had the CD key and security answer, and they said the same thing. I kind of felt like giving up on it, but I decided to make a ticket and live chat with them through the website, ON MY MAIN ACCOUNT WITH A COMPLETELY DIFFERENT NAME LOL, and the GM I was talking to had to be new or something because I mentioned that the account wasn't originally mine, I don't know the email, and all I had was the CD key and security answer.. He changed the email to something I asked him to without hesitation once I told him the info.. This just proves how broken blizzard is. All it takes is 3 tries for a hacker to get your account rofl.
tl;dr, blizzard is NOT brilliant.
