Cartrack, ABSOLUTELY worst Customer Service Ever

Phone to arrange a de-install and re-install on 25 November 2024, I got told to pay R600 for this to be arranged and confirmed. I made the payment on 26 November 2024, to date the the unit in the vehicle that I sold, has still not been removed, I can still track it from the web portal and app on my phone. I took delivery of the new vehicle on 2 December 2024. First installation date for the new vehicle was confirmed for 13 December, the technician was a no show with no communication from Cartrack on this. I had to phone them again, which in it self is the most annoying thing you can do, then got a confirmation for 6 January 2025 at 09H00. By 09H30 on the day of the installation I called again as the technician again did not show up only to be told he had car trouble and they are sending another technician that will be there within the hour. Again a no show from the technician I phone yet again to try and make new arrangements and was promised the installation will be done on 28 January 2025 at 15H00. Again the technician did not arrive and absolutely no communication from CarTrack to advise me of any issue and that the technician will not show up. All this nonsense while I am still being charged for a unit in a vehicle that I sold on 26 November and driving another vehicle since 2 December without a tracking unit. I just spent another 15 minutes on the phone that got me absolutely nowhere. Three times that I had to re-schedule my life/word/day to accommodate Cartrack who don't bother showing up for an installation that they confirmed. Who is going to pay for my time that got wasted by Cartrack being useless and inconsiderate. Will I be refunded for a unit in a car that was sold, which Cartrack was to useless to do the de-install.
