If you recieve something that is knackered (but still sort of works) and hte seller tells you it was fine when it left them what do you do?

This is twice it happened now. Last time i left a neutral feedback cos i gave him the benefit of the doubt and he responded with a negative comment callign em a liar...bringing my rating down therefore less liely to be sold to again.

I can;'t afford another negative. This monitor has a green line going down the left hadn side and some of the pins are missing..it works.but im nopt sure for how long. It crappily packed in a cookery set box and crushed (even though ti was couriered)

The seller insists it was fien when it left her. She seems a bit mental in ehr email.

I knwo even if i leavea neutral she will go for the kill and i migth as well say goodbye from buying on ebay again?

Should i just leave good feedback or none at all and take it?
