Well it sounds like you've been de-ranked... good luck with that, there isn't anything the policy enforcement team will do for you other than give you a ban... The only thing i would suggest is to send the ONE person who runs the entire COD4 server moderation
a twitter message and hope he resets your stats... also I wouldn't suggest playing on your main gamertag, if the name is de-ranked, chances are its infected too. That puts that annoying ticker on the upper right hand corner, even though you may not be able
to see it, and that will make people file complaints against you and you will get banned... ill pm gt the twitter name... Good Luck...
