As a long term trusted private seller I’ve never had any issue with eBay - but had a dodgy buyer who bought expensive earrings and claimed they were fake because the box was different to one she already had (so the box not the earrings!!). I had proof of purchase confirmed by the jeweller and eBay told me several times they would protect me as a valued seller then rolled over and refunded her. I’ve had to go through multiple hoops of explaining yet again what’s happened to find out what they’re doing about my reporting her. Fundamentally nothing so I have no comeback, am out of pocket on expensive postage and wasted hours of my life trying to get eBay to support me as a valued seller. Where’s Vinted!
