Halo 4 Campaign Legendary bugs/errors

So i’ve bought Halo 4 and around nov 9th today I just finished the campaign on legendary solo.

It didn’t unlock my Mark V helmet or Mark VI helmet after beating it.
It didn’t give me my legendary commendations due to the server errors on launch day or possibably because of other bugs.

I was wandering if a mod could fix this and fix the mark helmets not being unlocked and also the campaign commendations that haven’t been unlocked like they should.

It would really suck not get this fixed, I spent time and money on the product and I really do hope a mod can help me.
Please and thank you for your time.

Just re-do the missing missions, check your commendations.

If you want to unlock the Mark VI armor you need the Bromageddon achievement!(I’m not 100% sure though)

Own, why should I have to redo the missions? I spent money on the game and the bugs werent suppose to happen. Its only right for compensation for the consumer.

Same exact thing happend to me. Im really pissed off i spent all that time doing legendary and it says i only completed one level. Because that was the only one i did online. Apparently you have to play online, they better give the helmet to people with the achievement though. Im not playing that campaign again.

Wrong. Mark VI is rewarded for beating the game on Legendary (Solo or Co-Op).
