Bad experience with Car Track

I am deeply disappointed in the service recieved from car track. On the 5th of March they came to fit a tracking device in my vehicle and damaged a car part in my vehicle. They then welded the piece together claiming that the car won't have issues. Yesterday, my car refused to start. I live in Johannesburg and work in Pretoria. I needed to be at work at 6 today and when I call Car track to ask for assistance with travelling to work and back until they fix my car, I am told they do not offer that service. How do you not offer a service when I baught a demo vehicle from a garage and they damage it and unconvince my life, then expect me to make a plan?This is not acceptable at all. I hope management sees this and they fix my car ASAP. My car is a 1.5 Honda ballade elegance 2018 model. Till today, no one is communicating to me about when the part they ordered will be replaced in my vehicle.
