In August I was working toward the War Games Monthly Challenge ("To the Victor Go the Spoils") which would earn me 20,000 XP for 75 multiplayer matchmaking wins. I earned my 75th win in a Big Team Infinity Slayer match on the Wreckage map on 24-Aug-2013 @ 3:25pm (eastern time, game duration = 11m 25s). Once this game finished I saw the Challenge Completed message pop onto the screen, and the 20,000 XP were added to my profile ... raising my Spartan rank from SR127 to SR128. After I played my next match (a Big Team Infinity Slayer match on the Exile map -- 24-Aug-2013 @ 3:45pm eastern -- game duration = 10m 51s) I noticed that the 20,000 XP had been deducted from my profile & my rank had dropped back to SR127. Thinking it was a temporary glitch, I went on to play a few more Halo 4 multiplayer matches on Aug. 24th & winning several more of them ... but the 20,000 XP for the successfully-completed Monthly Challenge did not return to my profile. Does anyone have any suggestions on getting this issue in front of the right people at 343i? I openened an xbox live support ticket on the day the issue occurred, but the MS Support engineer just informed me today (via e-mail) that I needed to post to the 343i forums. (Which really isn't the same as opening a "true" HelpDesk-style ticket. :-) )
If anyone know a direct 343i Customer Support link or phone number I'd be very grateful.
Thanks for reading my post!
