Tracker doesn’t work and can’t get service to fix the problem

First of all, I used my tracker panic button once and had no response from the company, when I enquire from them, they responded that they tried calling but my cellphone was off (well of course since it was ****** in an attempted hijacking), I then left it as I was ok and only my cellphone was ******.

Now, a few months later I used the panic button again for roadside assistance, only to have them call me 5 hours later. My tracker is only sending the signals 5 hours later.

The issue could easily be resolved by replacing the tracker, assessing etc, but no! I cannot get service from them. Each time I call they say they are escalating it to a supervisor who will call me back and never does. Ridiculous and disappointing to realize that the tracker and panic button which I think will help me in an emergency is just a waste of time and money, also unsure whether I want my safety in the hands of such unreliable people who cannot even bother to return customer calls.
