Unhappy client

Today I tried using my panic button around 3 o'clock until this time no one has called me instead I called them only to be told that my system is being flagged for repair. What make me mad is that they never notified me that their panic button is faulty. I called the company and was promised a call back and it's over 2 hours no one has called me. To my shock when I got home I pressed the panic button of another car but still nothing. Cartrac is putting my life and family at risk. I am paying every month to be take for granted like this.
