The problem is the next, I already complete 1.000 matches on matchmaking. I already comprove it on Halo Waypoint Apps on XBOX 360 and Internet, and it say I have it completed. I also have the right code but when I introduce it, it says I'm still need to complete the 1.000 matches. I hope 343i cans help me with this problem.
