I went through the exact same thing years ago (1995 I believe) when they first introduced the "new" F-16, only then it was not e-mails, but expensive phone calls. This was before the kit was even out, I was on the pre-order list. The excuse list was long, but I did finally get it. Disappointed with the whole CBM thing and would advise everyone to just stay away and avoid the headache. It doesn't look like they have changed at all, but actually got WORSE. I didn't even have to wait a year on a non-released kit.
