Charged for a non-functional unit

Good day

This is my second review. Last year after I complained about paying for a unit that I did not have, the unit was installed. I then realized that the unit was not working and reported it to Netstar. They promised to send a Technician to check the unit and the technician never came. They kept calling me for outstanding amounts for a system that never worked. I was hijacked in July and I pressed the panic button with no response. To this day, the unit is not working.
