I don't have the skins I paid for

So this isn’t really much of a big deal. But I have the Ultimate Edition so I should have the Reach Characters etc.

What I have: Kat, Emile, Every Weapon Skin, And Banner.

What I dont have: Jack Reach Skin and Halo Reach Emile Bloodspray

Is there anyway to get this? Is my Ultimate Edition bugged?

I don’t even have the characters and I have the ultimate

I got mine, not giving a crap about skins tho, I would love to send them to you as a gift if I could.
