I have found the code you're referring to, and it looks like it was canceled, because it was purchased with a stolen credit card. In such situations, our policy is to cancel the code, and give the money back to the owner of the stolen card.
I would strongly advise contacting the third-party reseller, whom you probably bought this code from, and asking for your money back.
If you have any further questions, please either post a reply here, or send me a PM directly.

Actually, we're refunding the identified cases ourselves, without waiting for the bank's intervention, or lack thereof. ;)
