Adam at A of C has always been very prompt in returning my emails with questions. I believe he's based in the pacific nw and we've had some bad weather this week, with a lot of people without power. could be he's incommunicado because of that. Or he's on vacation. I also think it's a one man show, as mentioned earlier.
+1 to this. Give him a chance. I believe he will respond to you and provide good service.
