Good game, but can't unlock marine one – Independence Day Resurgence: Battle Heroes Review

I have recently bought Independence Day: Resurgence, I came with a QR code to unlock Marine One, and get free in game currencies. Problem is, when I scan the code it just takes me back to the product page and doesn't give me the extras I'm supposed to get. Developers, can you help me out with this?
