@Jevans1996zz You may have already redeemed the codes yourself. If so, they'll be linked to your EA/Origin account, and you can download the packs from your Origin library.
If the packs are not linked to your account, and you're the original owner, perhaps they're on another account. It's also possible that EA made a mistake along the way. Regardless, you'd need to contact EA customer support to get things sorted out. It would be useful to have any proof of purchase or ownership (photos of discs, case, insert; receipt; etc.) to show the person helping you.
If you bought the game secondhand, it's likely that the original owner already registered the codes. If so, you're out of luck. EA does not allow codes to be transferred from one account to another.

I don't work for EA. I'm just trying to help fellow players with their games.
