used when promised new

I ordered .5m pair of Cardas Golden Reference interconnects from an Audiogoner We negotiated through email and came up with the price of $375 NEW. Well, I got the cables, timely, but they are not new. They are in absolutely fabulous condition, but they are definitely not new. They were also packaged poorly with no Cardas literature. No nothing. I emailed my disappointment, and have not gotton a response yet. This is going to be my first time giving a negative response on "feedback." Isn't this appropriate, even if amends are made. Am I being fair? Is there, really, any reason to hear an explanation? Even if he makes good $$wise, he still lied to me. I would appreciate feedback from you guys.
thanks in advance,
