Hi, I recently acquired an unopened, shrinkwrapped copy of CoD Advanced Warfare for the PS4. I tried redeeming the Havok DLC using the voucher code provided, but it gave an error. Checking with Sony's Playstation support, they traced the issue to the code being expired, and informed me to contact Activision.
Is there a way I could get my expired code exchanged for a workable one? I can provide a picture of the game disc/voucher sheet if required.
