@si13nce No, sorry. We wouldn't be able to provide that on the forums.
You can try contacting support, but with these particular codes if there's an issue redeeming it you'll be redirected back to the retailer for certain vendors, Amazon being one in particular.
@keelfin
We're looking into a separate issue with coins being purchased directly through Steam, but that's not affecting the majority and wouldn't impact the ability to claim a valid code as in this case.
For codes not purchased from one of the trusted retailers listed in that prior link, you'd need to work with the retailer to secure a replacement code or for a return.
