DEVICE NEVER WORKED BUT BEING BILLED

Device was installed in December and having paying since then. I called to test the unit in May only to be told the device is faulty and the vehicle cannot be traced. So if my vehicle was ****** tough luck. So after a couple of broken promises that a technician would call me, after asking Netstar to cancel they agreed to look into a refund for me. The technician by the way has still not called me, and if I have to call and be transfered from one person to another then that would just iritrate me. So Netstar I am paying you but for no service and if thee vehicle get ****** today, it would ofcourse be of no fault of yours because your technicians are busy????
