Wells was one of the first on this site. I will vouch for him. As for having a full-time job, we all have some times in our lives where things get behind. Cut him some slack. If you insist on being angry - take it up with a lawyer and proceed with your BBB. Since you have his real name - it should be hard for you to track him down, but it must make you feel better to take it out in a public forum.
BTW - I can remember when he didn't take orders until they were built. Then he probably went and got an automated payment system (i.e./e.g. PayPal, C/C, etc.) and thus payments are taken immediately and he may not have the box built.
I'm just trying to help you see there might be a legitimate reason, and I understand there may not be. I suggest you look up Chris Wells and contact him directly. It isn't hard to get a phone number these days.
