I sold an item. Buyer took parts out from the item and sent it back to us, saying that item did not work, even warranty seals were broken. Ebay asked me to refund buyers money because it is ebay policy if buyer return any item as defective than seller has to return money including shipping cost. I explain ebay all the situation how this buyer is ripping me off but ebay has no way to find out who is wrong or right. Look like it is very tricky to do business on ebay. According to ebay recent policy you can easily ruin any seller or seller reputation, plus seller will also get discredit as reward. For me ebay is not good platform to do business.
