Grumble, grumble come on Audiogon

So I have been interacting w Chat room monitors about an advert that states "x brand equipment WITH accessory" (that is not the ad, but I dont want my attention to give the seller any more traffic, because I think they are being unreasonable.)

I put in a full price offer based on their description, and the answer came back .. "what about the accessory?" .. I said WHAT? and then explained the listing wording and the body of the description wording .. adding "Have you ever seen someone that says "car for sale w/tires" and then purports to change the sale parameters to then charge you for the tires?"
I am willing to let the sale go (their loss) but that vaguery would not get away on Ebay .. and I can not understand the Chat monitors who said the ad was taken down and its still up w/same language!
Come on A'gon ..
