hi I bought an item of art on ebay from a seller who did such a good job convincing me it was real, I tought thete was a 99 percent chance it was, I tought that i was getting such a bargain that I could resell it for a profit. I then resold it and made 100 euro. Now I really pitched well as I genuinely tought it could be the real thing but then I stated theres no authenticity so its sold as is, I have since found out that the person I bought it off is a con artist because he was tryin to sell me another painting, and he sent me two images, one of a stamped back of painting, one of exact same painting unstamped, so he is obviously stamping these paintings to make them look real to fools like me. now I have resold the painting but havent shipped yet, should I just cancel the transaction? refund the buyer? or will ebay see and think im a con artist, or should I just send the package? please help me out
