Temporary XP Ban

Hey guys, well today i logged on to Halo 4 and played about 2 matches of Flood (I got 0 kills because I was a n00b at Flood) and then a message popped up and said This account has been temporarily banned from earning xp. I dont know what is goin on but I bought Mt Dew and Doritos and I cant even use them. When can i get xp again
