I bought Destiny Collection for the PS4 brand new, sealed in plastic and everything. But when I try to redeem the code for the expansion packs, it says the code has already been redeemed. The other code(for the iron gjallarhorn) works just fine though. I don't know why it's saying the code has been used, I haven't used it and it was still sealed when I bought it. I can't figure out how to get in touch with Bungie, so any help here would be greatly appreciated.
