I sold a near perfect condition iPhone that was previously used by my family. It was sold to help raise money for a local resident in need. The phone is fully functional and works great, I tested it thoroughly since I work on cellphones and computers for a living. I shipped the item out and I saw the item arrived. Sure enough after Christmas, the customer opens a return case for "changed mind" saying they received new iPhones for Christmas and wanted to return the 6S. I politely explained I couldn't accept returns, I told her I had given the money raised to the local resident and could not get it back so I closed the case and refused the refund. A day later she messages me and tells me the touch ID was not working and would be contacting ebay resolution center to get a refund. I know for a fact the home button was working since I activated the phone prior to selling it to her and go through all the steps to test each function.
Is there anything I can do to protect my funds and feedback?
"Is there anything I can do to protect my funds and feedback?"
If the buyer opens a case for Item Not As Described the answer is no.
