You sold a part.
The buyer claimed it was broken.
You refused a refund.
The buyer threatened to leave negative feedback.
You refused a refund.
The buyer left negative feedback.
You used the threat to have the FB removed.
The buyer opened a Dispute.
You refused a return for refund.
EBay told him to return the part for a refund.
He pays for the return.
He has not returned the part.
No money has been taken from your account.
Frankly, I think the buyer is in the right.
For some reason, the part you sent him does not work.
Maybe it was damaged in transit.
Maybe he broke it while installing it.
But the pattern you describe sounds more like a person with a broken part that he paid $260 for and a stubborn seller who will not stand behind his product.
The first clue is that he went to Feedback, before noticing that he could open a Dispute. That's a pretty good clue that he is not used to eBay and it's resolution system.
20/20 hindsight: If you had told him to return the part for a full refund, you would not now have a Defect on your selling account for refusing a Claim.
At this moment, you are NOT out $260. He has not returned the part. Until he does, you are not required to refund.
When he does return the part, refund promptly. It might save you from that Defect.
If he is a scammer, he will probably not spend $60 to return the part. And you will not be required to refund.
Now.
In future, try to understand that this is business and not personal.
Not every transaction will go perfectly.
And this is where Cookie Jar Insurance comes in.
With hundreds of good sales, if you put a tiny amount, maybe a dime, aside for the occasional problem (late delivery, shipping the wrong part, damage in transit) then when something inevitably goes wrong, you take those dimes out of the virtual Cookie Jar you tossed them in and cover it.
Before the buyer leaves negative feedback.
Before the buyer opens a dispute.
Before you get a Defect.
