I got into a S&D lobby when a party full of hackers joined. I immediately exited the lobby. Then, a hacker sent me an ally request. His name was Anonimous or something. I didn't even accept it when a few seconds later I was disconnected from Mw3 online. When I reconnected, I was Prestige 3 lvl 1 when I supposed to be Prestige 2 lvl 67. I checked my stats and they were also messed up. I then checked my private match classes and the weapons were all lvl 31 with damage proficiency on. Now, I don't know what to do. If you could offer me any advice, I'd appreciate it.
