Tracker installation

This is a formal complaint regarding the installation of a tracker in my vehicle. I traded in my vehicle in December and requested Netstar to come and install the tracker in my new vehicle, till today I am still waiting. I followed up last month and I was told that tracker will be installed the next day, I am still waiting even today. I got a call from your consultant midnight telling me they received a signal on my vehicle (referring to my old vehicle that still has the tracker on that I am paying for every month). This is not right and if my vehicle gets ****** it is all on Netstar because my excess is high on my insurance because I don't have a tracker but I am paying every month. Terrible service
