Here is latest from eBay. To kick sellers where it hurt most.
" Negative statements within Feedback left for a buyer that conflict with the positive rating " will be removed.
So if you had a impossible buyer who demanded extra services and left you unfair neutral or negative you cant even warn other sellers by writing anything as such on positive feedback to him/her. So you either give a good feedback to buyer or keep your mouth shut and your miseries to yourself.
Save Sellers!
Case Study- "My recent feedback for wrangler top",
Buyer left negative asking why brand label is cut inspite of me clearly mentioning in my listing that label has been cut. and further it was me who called first not buyer.
