UNABLE TO TRACK MY VEHICLE

I have 5 vehicles that have tracker fitted and for the past few days on the Tracker App it shows my Mercedes is parked in a wrong street to where I actually live. So today I called Tracker to ask them where my vehicle is and they say they cannot locate the vehicle. I then speak to the Supervisor and she says she will send a Technician now and this was at around 12h00 and its 14h30 and no one has called. She also had the audacity to tell me I wont be charged and also when I asked her about the payments I am making for monitoring she begins to tell me about her Terms and Conditions and yet there is no Terms and Conditions if the Unit is not working you just have to pay. Absolute ******* Now lets see if anyone cares about their customer service and see if they contact me. Car Track here I come, been with Tracker for 8 years.
