Poor service recieved

on February 2020 a tracking device was installed by Cartrack in my Vehicle, same day I started to experience problems with my car where by it would just turn the lights on by itself and also the wipers would go on, i reported the matter to the Mthatha branch as it was them who had installed the tracker and the same technician came to fix the error, but i noticed after he left that the problem was still there and i was also struggling to start the vehicle, i would have to turn the ignition many times before it starts, i reported the matter again to their head office and i was assisted by a guy called Juante, a second technician from Durban came but he also couldn't fix the car, then the following day the car got worse it couldn't start at all, again i called them n a third techniician came n he noticed a fault in the wiring of the car which ended up burning the starter. so they towed the car to East london for repairs, it took them up to May, since February to tell me that the problems in the car were not their fault. so they can't pay for repairs, i asked for a report from the workshop where the car was fixed because i ended up paying on my own because i needed the car for work, i never got the report until today, instead they called to tell me that i must pay them R7500 for towing my car.what the hell??? Cartrack i want my 7800 that i paid to Meyers motors to fix my car or else after the lockdown we meet at the ombudsman's office or the court.
