Amazon didn't really help, but the buyer was understanding luckily.
The buyer is apparently is a reseller (his amazon account is a business account) and the customer he had sold them to returned them to him, so he returned them to me. (which i don't think he should have done in the first place)
But he was kind of incredulous to my claims since I had already refunded him partially and complained about the cigarette smell, but after showing him the scan comparisons, the human hair behind the plastic cellophane, etc, he agreed he was scammed too.
I don't know if all that is really true, but he agreed to return the money to me so Amazon is facilitating that now. I'm just sending these copies back to him along with the video of me opening it as he claims he wants to use them as evidence against his customer.
EDIT: Oh, the disc is blank. :)
