So this is a post to officially complain, as well as offer solidarity to those that are dealing with this problem right now.
My account was taken over September 9th. I found out because I got a phone call from my bank alerting me to suspicious activity. They charged 75 dollars (4000 point, 1600 point and 400 point) and used my gamertag to purchase the games. I wondered why they didn't just transfer off the points. I was still able to recover my account, change all the information again, and lock the account back down. I also managed to do a license swap so the thief couldn't use the games he bought.
To my knowledge there wasn't a region swap (I'd assume I'd know if there was a change or not) and I called Xbox to alert them to the problem.
They locked the account down to begin an investigation, and it's currently still ongoing. About 2 weeks into the investigation apparently they needed another separate Email to contact me from, but I don't know if this reset my position in the Queue, or completely restarted the investigation process.
It's been 35 days since the beginning of the investigation, I'm still out money (I hope to finish the dispute with my bank tomorrow) and there are still no answers.
I don't think this is associated with the recent EA Fifa ordeal seeing as how the person played Shadow Complex and Black Ops with my account, and just bought a bunch of regular games off XBLM
I'm 31, I don't even have many friends on my list other than personal ones I see regularly, I certainly never outright shared my account info with anyone, but I can't be sure whether or not I never used the same Email/Pass combo for another site I visit regularly.
Hopefully I hear something tomorrow.
I'm going to give it another week though, and if nothing comes about I'm going to escalate it with complaints to the Missouri Consumer Protection Dept at the Attorney General's office, along with a BBB complaint, and most likely the filing of a small claims court case.
