Memories of reach pack bugged?

I have collected every single pack in the game. I just need the halo reach armor pieces, but all I get are weapons and vehicles. It says you have to open it seven times to get the full set, but I have opened it even more than that! I feel scammed, I just want my reach armor. I feel that the memories of reach pack is broken or something.

Specifically, what items are you missing?

Chances are, the Reach items you are expecting from the Memories of Reach pack are actually the Classic Helmets, which can only be gotten in the Classic Helmet Pack.
