Has anyone here had trouble with SmartShoot?

I've had five out of six shoots fall through for me. The first client I had was perfect and the shoot wasn't perfect by my standards but it worked out. After the first shoot, every single client after that backed out for one reason or no reason at all. They either would not answer phone calls, reschedule the shoot 2 or 3 times then be a no show, or they acted like they didn't order a shoot. I'm done with this site and I'm looking for other mills like it. I know my area likely has more photographers than work but I can't move to a bigger city.
