Poor and ******** suspicious service by Netstar

Poor, I had an early warning system installed in my vehicle as an upgrade. The unit was installed on 21/05/2021. I registered with online application and tried to test the installed system but I have been unable to locate the vehicle. I called Netstar for numerous times and Netstart was also unable to locate the vehicle. Netstar agent committed to have a technician sent this past Monday 31/05/2021. To date no one from Netstar has contacted me. I called the installing technician who had committed that he would be available to assist if I called him but He is not answering his phone. I think Netstar have a plan to ***** or hijack my vehicle because Netstar know it will not be lacated yet I am being expected to pay for the service. My number is ***
