13 days seems like they were really giving you the run-around and still deciding whether or not to keep the snake... Obviously they weren't very motivated in the first place to sell it (and still flip-flopping in their mind) if they couldn't at least provide you with the reasonable basics any interested customer would request.
I guess the one good thing is no $ was put down (which I would never do either, if I hadn't gotten the specs). If it were me I would post an "info" thread about this seller on the BOI because of your wasted time. People can draw their own conclusions about your info, but at least it's there.
