Heard he has done this to many sellers. He will pay via Paypay and later will claim a chargeback by the credit card issuer. Sellers can't do anything with that, coz Paypal has contract with Credit card to protect buyer on this. He will claim with the credit card that the payment was unauthorized... and sellers will be charged back plus $10 for the charge back fee... no matter even you have proof that the buyer has received the goods.
