Stats are Absurdly Wrong

Can someone explain the following to me? My War Games stats are, at least on the front page (that has games played/won/kills) so absurdly wrong it’s laughable. Thsi happened about a week ago, and it changed instantaneously. It says i’ve played 15 days when I’ve played maybe 1 and a half. It doesn’t match my K/D, it doesn’t match my weapons kills, and it doesn’t match my game history. I’m getting pretty annoyed at having a completely useless stat page. Can anyone tell me what’s up/help me/tell me who to contact to fix this?

Thanks!

did you ever figure anything out on this? I went in to get my “First Strike Mastery” which shows I have 50, I looked here and it showed I had 48… I got my last 2 and puff… nothing. So I looked on Xbox and it says I have 11. I just started playing Flood because I knew I had to be close. I know I don’t have 11… but no clue how to fix.

Proof?

Should you start a handwritten diary of your personal Halo 4 stats for when something like this happens?
