When a transaction goes south, such as this one, a good seller (in my opinion) should respond with something like "I'm sorry for the misunderstanding. Is there anything we can do to make this right?"
I agree with RRR, the seller got real defensive, real fast (when he finally showed up), and had no intention to try to make things right until he finally caved in to the general consensus that he was in the wrong. I've got a list also.
