Paypal should be able to file a response to the credit card company on your behalf. You should provide paypal with whatever evidence you have of the transaction so they can send it to the bank.
The likely problem is that if the buyer says the card was stolen or if the card was in fact stolen then you will likely lose, and would need to take legal action against the person who actually received the goods you sold.
Exactly, PayPal has to receive the evidence. I know PayPal often sides with the buyer. But if he - in this case - really can provide videographic evidence that he really shipped the merchandise, wouldn't PayPal protect him as well?
Ebay/paypal should have all the evidence they need. Ebay knows exactly what item the scumbag bought, tracking is uploaded and shows that it's delivered. The account is brand new with zero feedback. Ebay knows all this. Paypal knows all this too because the transaction is linked to ebay.
The problem is that he is filing a chargeback through his credit card. His credit card decides the outcome, not ebay/paypal resolution center. Even if ebay/paypal knows it's fraud, they are at the mercy of the credit card company's decision. Paypal has already withdrew the amount that scumbag charged back, most likely because the credit card company will side with scumbag. If they truly wanted to investigate, the would at least wait for the outcome before taking my funds.
