Buyer offer accepted but then buyer did not pay. Can I leave buyer negative feedback?

[jamleigh]

Buyer accepted my counter offer but then decided not to buy the item. Reason given was that after ‘buying’ my item (and not paying for it) he/she was no longer interested because he/she had ‘now found one cheaper’.
I want to leave negative feedback but do not seem to have that option?

The way to deal with a non-paying buyer is to open and complete an Item Not Paid case in the Resolution Centre:

http://resolutioncentre.ebay.co.uk/

If you do that your selling fees will be refunded. More than that though the buyer will be given a defect (black mark/ demerit) on their account.

If they do not pay another seller in the next 12 months and that seller completes another UPI case, that will restrict the buyers buying activity severely as sellers can block buyers with two black marks on their account in 12 months.

Have you set up your account that way?

Add the buyer to your BBL.

Don’t be tempted to retaliate by buying from the member and then not paying. That is also against eBay policy and can severely damage your own account.
