Worst Service - empty promises from a technician!

I am paying for Warrant Quick Management Plus Package (R219). For the past weeks the App is showing my car a 100km away from where it is and I cannot switch on Car Watch Alert as the device is faulty. I called Cartrack on 14/07/2023 to fix this and the appointment with a technician was scheduled for 20/07/2023. A technician by the name of LORENZO CONSUL was assigned to come at 10H00. He called at 9H42 to say that he is running 1 hour 30 minutes late! At 11H30 He did not pitch, and I had to try and get hold of him. I eventually spoke with him at 1PM and he promised that he will come before 2PM. He never came! I sent him a sms and a WhatsApp message begging him to come as my car is at risk. He called at 13H26 saying that he will come after hours. I stayed at work after 16H30 until I left at 18H00 as he never came. He late called and said he will make it on Friday morning 8H00. Instead of LORENZO coming, I received a call from Cartrack saying they can schedule me for 26/07/2023. I was told that a manager will phone me, I am still waiting. So, I must wait another week while my car is at risk. The only thing I received from LORENZO CONSUL was empty promises, denials and lies!! If this is not resolved today, I am taking it further. Should my car get ******, it will never be found as the device installed is faulty. When going to a shop I cannot even switch on Car Watch Alert as the device/ app always says my ignition is on, while it is off. I am extremely dissapointed!
