Non paying buyers

[xthejbm666x]

Why can’t I leave negative feedback on the buyers account after they refused to pay???

buyer made ridiculous excuses to get out of the auction and I’m out of pocket

Sellers haven't been allowed to leave neg f/b for buyers for years.   Be sure to issue an Unpaid Item cancellation after 4 complete days.  That will put a non-payment "strike" on their account which could lead to their account being suspended.   More info:

Don't forget to put their ID on your blocked bidder list:

And use this link to put a general block on buyers with a history of non-payment, etc.:

tick "Update block settings for active listings" and then save changes at the bottom.

adding to the advice already given -

eBay stopped sellers giving buyers bad feedback over a decade ago because sellers abused feedback and your feedback proves eBay were correct.

The auction only ended today.

The false positive you left the buyer is serious feedback abuse and revealing the buyers actual name is extremely serious violation - if the buyer reports you it will damage your account.
