received 2 emails last night both saying thanks for purchasing 5000 microsoft points ! I switched on my 360 to find I cant get online as user information is invalid ! it all looks like I have been hacked ! I went on my xbox account on my laptop to check my account which says I have 2 transactions for 5000 points and that I have purchased games and game addons incl Call of duty black ops game download which I already have the actual game !!! I tried to delete my credit card details but that wasnt an option so changed passwords and logged an email as the help line shuts at 10pm. Funny thing is market place is down ! is there a link between my issue and the market place ???
