I rated them high on Friday but changed my mind

I rated them high on Friday but changed my mind. The guy was very friendly but what I was promised was not what I got. I was told that they will come and install my device yesterday, but when I phoned them the guy told me when it's convenient for them and the guy is in our aeria they will come and install the device, not when it's convenient for me but for them So after 15h00 yesterday the technician arrived and installed my device. Yippee No, not Yippee. Today, I discovered that cartrack can't track my car and don't even know where my car is at this moment. I am talking to Katlego but not a manager as requested. Every time I ask for a manager, I get a different answer. If my car get highjack today, where will they find my car or who will be responsible for replacing my car.
