I sold a pair of christian louboutin on eBay, normally I don't do international shipping but she really wanted to buy so I made an exception. She paid me $35 shipping but then it cost me $62 to ship to her country (Kazachstain) I sent her receipt and everything since I purchased from Chicago store. And now she claimed it fake and opened a case to request refund ( I think it's more like buyer remorse) and I don't know what to do, please advice. Thank you very much
