Appalling call out service and technicians

Appaling service. We have had a GPS tracking unit in our vehicle for 4 months. The battery is already flat, and subsequently draining my vehicle battery. We requested a technician to come resolve the issue to which we were told a technician will come on Monday (15/01/24) at 5pm. The technician never arrived and when calling the call centre, they could not tell us where the technician was and couldn't get in contact with him. We still dont have a date for when the technician will come while in the mean time my vehicle battery is running flat thanks to the tracker for the second time in a week. Netstar needs to improve the quality of their device battery's to actually last and do what they meant to dobefore ibwoukd recommend them to anyone. Im not even going to start on the attitude and service from the technician that installed the unit. It would be appreciated if they could stick to what they say and come sort their issue out.

The panic button they con you onto buying is another joke. Of my families 3 vehicles, only 1 works. When all pushed within minutes of each other to test them as instructed. Only 1 signal goes through. What a waste of money.
