I hate to ask but did you ever reset your stats or were they stats ever corrupted? If not you must rank up pretty much the same day. Something is messed up. I have not reset my stats and they haven't been corrupted that I know of. I made the account 3 or 4 weeks ago and have been playing daily.
Can someone help me figure out why I can't rank up, at all? I have 18,000 kills, 48 downs yet I'm stuck on the first rank (single bone). I called customer support and they said there is nothing wrong with my account, which seems odd. Could it have something to do with the fact that I have multiple accounts on one xbox? Any help is appreciated.
