Appalling service from Leading Brand

I am a first time customer of Tracker. I purchased their flagship SKYTRAX package on the 24th of November 2015, so that I am able to track my vehicle online. I am running a small fleet of cars and I need to know the exact whereabouts of my car. <br> <br> The device worked until the 1st of December, thereafter I could no longer track my car's movements. When I inquired with Tracker, they confirmed that they are able to locate my car, however, there seems to be a problem with the device and that a technician would call me to come out to check the device, three working days from the date of my call. I did not receive a call by midday on the day of the appointment, so I called Tracker to inquire. They provided me with the details of the fitment centre, who advised that they had only received communication from Tracker that morning, but were willing to help me if I brought the car in. The car went in to Motor Sonic, Edenvale yesterday, to fix the issue. After 2.5 hours the problem was not fixed, and this was not communicated to me! Time was wasted and money was lost!<br> <br> Tracker, kindly get this issue sorted out as I paid for the device upfront. This is ********** customer service!
