Bad customer service

My cartrack device installed on the 12th of September 2019 by werner Taute, it worked perfectly for two weeks after that I noticed that the red light by the right hand side was no longer flashing so I pressed the panic button and I got no response, I then call customer car and a consultant told me that they will send a technician but he/she was not sent, I feel that I'm paying for nothing, what will happen if I'm really in trouble I'm currently not using the car, because I'm in fear of what might happen to me. I left a message for them to contact but they take their time to respond I'm not happy with level of service they render.
