Well...did he do these type of things ? I know when I got sent a bad gear reduction gearbox he immediately refunded my money and promptly banned me from ever buying from him again without so much as an explanation. The only way this got fixed was when Gil intervened and squared it with Jin. Otherwise I was treated like eBay is now treating Jin.
EBay can be incredibly pro-buyer and will turn a sellers world upside down at the mere suggestion of improprieties. I haven't sold anything on EBay since August 1st 2023 when a scammer took over my account & EBay didnt care to help for 6 months.
