That is the thing that drives me nuts. A seller is going to leave a negative feedback because he received one?

I purchased some chipe that were listed in "mint condition"- when they arrived they were chipped and table played with plenty of finger dirt. Ended up they were drop shipped and the clown never even had them in his possesion to be making condition claims of "mint". After many emails back and forth and essentially getting a "too bad" response, I left a neutral. He was then pissed that he had already left me a positive feedback, would have left me a neutral as well. Why? My end of the bargin was held up- it was his that was poor. Wish there was a bette way of holding some of these sellers accountable.
