the fact that your antenna stays up has nothing to do with how the radio normally operates. It should go up and down like normal. Either the turn on wire was hooked up incorrectly or your antenna motor may be fubr.
The reason you likely paid so much for installation was the fact that you didnt buy from them. most shops will add a pretty hefty "bench testing" fee if you bring your own stuff for them to install.
What install shop did you go to and where?
