Disturbed customer from pathetic service received.

On the day the tracker was installed the technician broke 2 clips on the inside of the car, which I reported and to date I am still waiting for his supervisor to call me back. on the 26.04.2019, my batter was ****** from the car, I never received a call from car track to enquire why the battery was being moved, I then called at about 2 pm, to the call centre the first agent that pick up the call and asked for my details said that is the tracker registered on my name as she could not pick up my details, I was then cut off. the second call I made I was put through an agent that picked up my details and advised that my car was about 5 km from me in a township, I asked to speak to a supervisor and as usual with call centres supervisors are always busy in meetings. she then put me through another person in the control room who advised that I will receive a call from a superior as to why I was not contacted when I battery was ****** and it is now 2 hours later I am still waiting. I must say that the service is pathetic, they never get back to clients and their response to questions is very shocking. Either they just want the business and no after service or they just do not care about their clients. For all my car could have been ****** by now and they would have still not contacted me. So, the question I have to ask is am I paying for a tracker that is installed in another car? Why the pathetic service? Who now covers the cost of the replacement of the battery? Can I get a call from a senior person from the company that knows what is happening and give me answers to my questions.
