Poor service and disrespectful of a client

I have been trying to get an issue sorted over 2 months if not more. The tracker that got installed in my car is draining my battery, two people from Cartrack came to check and recommended a wireless device to be installed, and further requested that I get authorization from my insurance which I did and further called the technician that was here to proceed. To date no one has called me, I made constant follow ups with no response . I am a woman in South Africa, this is causing safety issues!! I am also a paying customer who does not deserve such poor treatment and disrespect.

Can someone sort this out urgently, please!!
