eBay looks after eBay, not it’s loyal sellers who’ve been around for 15 years. Refunding my money willy nilly to impatient, nasty, paranoid buyers who want the item for free because there have been the worst postal delays I’ve ever know due to covid lockdowns on top of the Xmas rush, and they’re too tight to pay extra for tracked mail. Those buyers get the refund which eBay bullies out of the seller, and get to keep my items when they arrive late too. Not fair when the problem is Royal Mail. I have proof of postage but they’re not interested. I’m going to Etsy and Facebook marketplace instead.
