I got hacked, not phished. I've never been on a phishing website in my life and can spot them from a mile away.
So take your sympathies, or lack thereof, and move along. This time is hard enough without people like you chiming in and blaming the victim.
For the record, my account got hacked and the profile region wasn't changed (thank goodness). I started my UA case on the 29th of October and will definitely be making a thread here when I eventually get it back.
The guy spent £80, which I caught instantaneously after I woke up in the morning. The bank had me sorted out with a quick phone call and paypal also were extremely helpful. It was a typical FIFA 12 hack where the guy blew all my points on FIFA 12 gold packs.
I will reserve judgement on Xbox support until I get my account back, but so far they have been helpful.
Hearing all these horror stories of accounts being locked down for months on end tends to dampen my hopes, so I will be following xbox support up every week of my investigation.
