Hi guys I just have been scammed. Or.. I will have the answer on monday when I call PayPal. So. I wanted to sell my knife and this guy added me. He sended the money through paypal and on the money'transfer, he wrote a note that said he traded a knife with me. So after I recieved the money, i traded him the knife (I have pictures of our steam chat and picture of the trade) 10 minutes later, I could see that he tried do pull back the money by creating a case on paypal. So now I have to proof that he actualy got the knife. Do you guys give me some help of what I should do and say to paypal?
