Missing DLC Help

I was lucky my enough to get a code for the E3 demo racing gear while at PAX. Unfortunately the racing suit will not show up in my inventory. I’ve downloaded and installed the suit, uninstalled the suit, and uninstalled the game and it still won’t show up even after reinstallation. In my inventory there is a icon for a “new” suit every time I log in but there is nothing there. Any suggestions or help on who to contact would be appreciated. I looked at the support page but I could not find out where to go from there.
