Not sure if this is the place to ask this but I am really frustrated and any help would be appreciated. My son was playing COD4 multi-player and someone by the name of [mod removed] hacked his account. My sons rank has been reset, his XP points are minus a million and something, the player match playlist is all greyed out and there is a vulgar message of the day that I cannot get rid of. I need to know what can be done to reset everything. Any help would be appreciated.
