Maybe they are just aloof, some people have to do all the work in a relationship, have you ever said, "hey guys I wish you would call, write and email more, I feel like I am doimg all the work".
I don't know why the cheap tests would not be relaible, check references, angies list, the BBB etc.
Wish I had some insight, but without being there it's really hard to tell.
I know this, if you need me I will be here for you.
Big hugs,
Bill
