Too bad? Sounds like you dodged a bullet.I have run in to the same problem, even when they have been active on the site. They mentioned they were busy, but I've never had someone so busy that they never returned after multiple communication attempts. And too bad too as I was going to buy a lot of stuff from him.
Just a tip from dealing with a ton of members over the years.... I did this but that doesn’t help much once you have bought something and cannot get the member to respond
