Service Record Problem (campaign)

The service record has that i have only completed 6-8 of the legendary missions when i have completed them all twice and have the xbox live achievements for them. I want my helmet and service record fixed.

I’m have my Terminals not showing in Waypoint Classified , But are listed in Achievements . How can I get that fixed ?

I’m having the same issue as infinite. And I’m honestly livid. I"ve completed the campaign twice solo on legendary difficulty with absolutely nothing to show for it except the achievement.

I have all but one more achievement to unlock on Halo 4 w/DLC. I’m not given credit for unlocking these achievements that came from the DLC. What gives?
