If it were me, I'd be making at least one call the this seller & note the date/time/etc of the message left for them or the person talked to. After 2 wks of no repsonse to emails, I'd be hard-pressed to call more than 2 or 3 days in a row. If I still received no response, I'd out them on a post (if that's allowed on this site) & include the emails, etc and ask them if they'd care to respond to that. Of course you'd have to mail them a link to the thread. If that isn't allowed here, I'd definitely make waves and start posting on Craigslist in the city they live in. Post in 'farm & garden,' 'general,' 'pets' and even 'rants & raves' to let people in that area know what kind of person this is. But make sure you state ONLY the facts, no name-calling. You could include e-mails there as well, just 'x' out your personal info.
But that's just me...
