Expired Redeem Code Battlefield 1 Revolution

I recently bought BF1 Revolution online and after a few days I decided to redeem the DLCs using the code in the box. At first it didn't work because my account was in the wrong region so I made another account with a different region and now it says it has expired. I checked the expiry date in the box and the code actually expired 2 years ago. I checked the online website I ordered it from and after reading their rules, I don't think I will be able to get a refund/replacement. Is there some way I can get a replacement code from EA?
