Not sure what to make of this. Today my usual gamertag wouldnt let me in, but another profile was allowed to sign in and play. I checked my e-mail first to see if I'd had any strange updates, and then found that 5600 xbox points had been purchased (no one in the house bought points). I checked my online bill, and then discovered the points had been refunded. Ok, but the profile issue is still unsolved. I've sent a message to the xbox people and haven't heard back yet. They probably busy, and I figured I'd see if anyone else had seen anything like this.
