After going back and forth a few time, it was obvious the seller wasn't leaving feedback until she got hers, so accordingly I left this negative:

"Refused to leave feedback. Insisted on getting hers. Feedback 'ransom' artist."

And she did the same:
"THIS IS A BORN LOSER AND THREATENED ME AND HE THINKS HE IS MR. EBAY."

Hate to be so hard-a**ed, but this contravenes the whole buyer/seller relationship.

Yeah - I threatened her with a negative, which she earned. I never make threats but I say what I mean and I mean what I say. Talk is cheap until you talk to a lawyer. Money talks and BS runs the marathon.

I get to respond to her comments. Anyone have a choice 80 characters that are succinct?

Born loser? Mr. eBay? Why because I asked her to do what eBay suggests and what everyone so far has agreed is the proper procedure?
