Redeeming various sets error "Our Servers Cannot process your request"

EA is trying to rip people off from what I can see. I can't advance my team unless I buy boss packs from the store, when I could just redeem them from the sets but it won't let me.

The game keeps giving me that same tired * message about the servers can't process, but I'm sure the store servers can process anything you won't, so why not use the same servers for the rest of the game. Mabey that is to simple for EA to process.
