Battlefield4 map packs

[NinjaPerkins]

Hi, my name is Makesi Perkins i live in Trinidad and Tobago. I bought a china rising limited edition battlefeild 4 for christmas. Its supposed to expire today but as soon as i ordered it online and i got it brand new it said it was either already used or i typed it wrong. I heard some talk about only certain regions get map packsso i wanna know if there is some way i could get another code that would work in my region or to not buy and map packs.
