How do contact eBay about negative feedback left when you dont agree with buyers comments for negative feedback. It feels like buyer can comment and seller has to accept it no matter what.
There is nothing there against ebay f/b rules. It sounds more like the buyer is saying it probably happened in transit. Of course they should have contacted you first but your reply is a bit OTT. If you can sort things out with them you can ask them to remove it. You can send them a feedback revision request via the link on here: https://www.ebay.co.uk/help/selling/leaving-feedback-buyers/replying-feedback-received-item-sold?id=...
your reply to the neg shows you in a very bad light and, much worse, the insulting false positive you left the buyer will cause you serious problems if the buyer reports it.
