My can no longer access Call of Duty 4 Modern Warfare via Xbox Live. He was playing on-line in a lobby and after killing someone and getting killed himself, he could no longer access the game on-line. His rankings were also deleted. He can still use the gamertag for other games, but would like to use the same gamertag for this game. I contacted the Xbox LIve Help Desk (Reference # 1154385251) and the representative told me to submit a request in the on-line forum (Account Suspension/Live Enforcement Team) because there was nothing she could do except tell him to start a new gamertag, which is not a alternative. His friends and the representative think he was illegally modd'ed. Can you reactive his gamertag (Bobby8799) for Call of Duty 4 Modern Warfare ? Thanks.
