Hi there   - - - - So yes being a buyer and a seller I get to see both sides. I have had sellers promising a refund and not doing so then once the 30days or 60days lapses there is nothing you can do. You can't file a claim and you can't leave any kind of feedback.   However you can appeal a PayPal claim. This can be done if the item received from the buyer is not in the same condition as what you sent. Essentially the claim they made against you is the claim you then make against them.   As for the negative feedback, cancel the transaction and then they are not able to leave feedback. Also if the issue shows as resolved in the resolution centre I don't think that eBay will allow either party (you or them) to leave negative feedback.

quite a few inaccuracies in this post..

especially the 'cancel the transaction.... comment

a Seller cannot just 'cancel' a transaction. the only way to stop a neg f/b is by opening and closing a Non Paying Bidder dispute, but as this item has been paid for that isnt an option.

a Mutual Cancellation request, even if the buyer agrees, still leaves both sides free to leave f/back.

and as for the I have had sellers promising a refund and not doing so then once the 30days or 60days lapses there is nothing you can do. You can't file a claim and you can't leave any kind of feedback.

as the buyer the choice of when to open the dispute is all yours.  if the buyer is promising a refund and you dont get it immediately, then you open the dispute, they'll still have 20 days to either refund or you close the dispute and get your $$$ back. and you can leave f/b.   the ball is in your court, play by the rules and you wont have problems.
