Lack of accountability by netstar.

So for the past two years netstar has been billing and debiting my account for service they are not rendering! Contacting them to even upgrade their device is a nightmare I'm sure why are they still taking money from me because honestly their service is just lousy. I believe it's time I take my money and go somewhere else. Panic button is not working, the arming device is just a decorative piece and nothing more.
