UPDATE: So I did write him and waited. And waited. Finally, I took a risk and e-mailed the owner of the place he bought it from and explained the whole situation. I made it clear that I was in no way inferring that one of his employees had over-stepped her boundaries, but rather the seller was waivering. He wrote back within 30 minutes explaining that what the seller had told me was not true and that they had never offered to take the guitar in for consignment. Rather, he had called them about a Martin and asked what he could get for his Maton. All they did was give him a ballpark and that was it. The owner's view was that I was the rightful new owner of the guitar and that the seller should honor the sale. Phew. Good to now I was on the right side of things. I re-wrote to the seller expressing my views and told him he needed to get in touch immediately. I was prepared to ask for my money back, but within the hour he got in touch and told me he's going to honor the sale and ship the guitar to me tomorrow. I asked him to send me tracking info, and if I don't get it tomorrow, I'll be all over him until the guitar gets here. Never a dull moment.
