I sold a item on Ebay and used Paypal to collect the payment. The buyer paid me quickly on paypal and I sent him the computer. I then found out the buyer hacked into someone else's account to pay me. Paypal reverse the transaction and now I am out $800 and my computer. The problem is that paypal's investigation process took 1 hour and they say that its my fault for not taking the necessary precautions, which I understand. I am refusing to pay my negative balance- is this a worthy fight or should I just lay down and take it?
