To me, there’s a lot of bait and switch in this process, fees are not fully disclosed. they say one thing and do another and you have to work very hard to get these corrected. There is no live person to talk to once you sign up. It is very difficult to get a human being on the phone. I had to call from a phone line that was not mine in order to talk to a person and that’s not the way a service that requires interaction should be.

The installer was convenient by providing remote installation, however, he did not show me how to use it before he left.
