Halo 4 legendary campaign armour problems

Hi all,

Iam writing this post in the hope that someone will be able to help me as iam very dissapointed that even after all the time I took to complete halo 4 on legendary solo somehow my legendary armour and visor have not been unlocked.

After I completed the game I checked my records and my commendations say that I have not completed the campaign on legendary but my service record says I have completed them all. I dont understand how this can be and why I have not recieved my armour. Can someone please help me with this problem as iam really dissapointed after putting in all the hours to try and get that armour.

regards,
Brandy I
