Banned for no reason!

Hi, I just bought the game and I have to say, Fantastic job. But, when i was playing with a friend online I accidentally killed myself while trying to get to the enemy team.I was then kicked from the game and I didnt think a thing of it. So, I start customizing my Spartan, next thing you know I am banned for no reason until 6:44.

Please use the ban thread pinned at the top of the forums for further assistance with matchmaking bans, thanks.
