Sold a used item on eBay, buyer wanted two for that price. Buyer demanded a refund, so I did what eBay told me, refund the money, even though it was stated no refunds or warranty. Now I have to pay for the shipping back to me, when I was told I could keep the shipping and handling because of the buyer remorse. After spending over 5 hours on the phone going back and forth with eBay, the customer service is the worst including the supervisors that never called me back. I even opened a dispute twice with no resolution. I guess I will look at other remedies for all the nonsense eBay has caused me. BEWARE of eBay ! Everybody you talk to @ eBay will tell you lies just to get your money !
