Well, I would be upset about issue #1.  But so far as the second, just let it go.  You haven't really lost anything but a few mintues of your time that it took to respond to the questions.  It's also entirely possible that they are still in the selection process.  I remember having responded to someone and got a reply back a few days later asking me some questions which I answered. But it was about a week before I actually heard whether I was accepted or not.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
