Failure to install a unit

October last year I purchased a car from Audi Wonderboom, I called tracker requesting them to cancel the current account I had with them so that I can start with the new account for the new car, then I was told that there is no need for me to do the cancelation Tracker will just have to transfer the device on to the new car, I notified the dealership and gave them Trackers contact details, on the 17th when I went to pick up the car I was told that Tracker had indeed contacted the dealership and told them that the device had been successfully transferred, the dealership said that I can take delivery of the car as the tracking device has been fitted and working.... Picked up the car, when I got home I went on to the Tracker app to make sure that indeed the car is being monitored, only to find that the registration on the app is of the new car but the location of the car is not of the car in my possession, the data is for the old car. I packed the car in the garage did not use it, I called Tracker from 18th of October 2024 telling them that the device in the car is not working, I also asked them why did they tell the dealership that the device was working when it isn't working. Tracker promised to send out a technician to come check it out because they could see what I was telling them about the data that they see as being for the old car, I kept calling Tracker regarding the situation and nothing was done by Tracker, now being scared that I have a car that doesn't have a tracking device, on the 26th of October 2024 I sorted another service provider and on the 28th of October 2024 the tracking device from another service provider was fitted in the car... Few days later I had a call from someone who said that they were sent by Tracker to come and install the device and I said that I already have the tracking device. I did not breach the contract with Tracker they did, had something happened to the car while it did not have a tracking device who was I going to call?

I have been with tracker since I bought my first car, I bought the service for 2 years in advance for the first car, and when I changed that first car I was told that the service or account cannot be transferred so I got another device for the second car which everything was done properly but for the third car it was just so disaster not professional service I received from Tracker.

I didn't want to be in a possession of a car that didn't have a tracking device which I am still paying for.
