What's up With VTS?

I realize he's a one-man operation, but I've never had trouble contacting him in the past and he always returned his missed calls. I've been trying to contact him weekly for months now. I have doubts that he pays much mind to his website. Something isn't right.

I understand his business model and have been trying him by phone - figured that was made clear in my second post. When one tries each week for a few months, usually at least twice in a given week, and still can't make contact, what is one supposed to think, the guy is just on one super long vacation??? Guess I'm just extremely unfortunate with my timing everytime I call. 

Yesterday when I tried calling multiple timee, hours apart, it wouldn't even ring. The dial was followed by a brief silence and then a disconnect with a "line busy" notice. I get that he's old-school but would a voicemail be asking too much? Maybe next time I should send a letter by horseback.
