Non functional vehicle post installation and a nightmare of a process with netstar

If I could rate it zero I would still be being too kind! It's been weeks and I have been waiting on a report for why my vehicle isn't working since installation of the tracker, they do not send feedback, do not respond, but yet make multiple visits to the dealership where the vehicle is currently being diagnosed at my expense, why, God only knows ! VESA has requested reports to no avail. Previously they had sent out assessors with no diagnostic tools both of whom made accusations on the car being driven too wrecklessly during a test drive that's why it doesn't work or the cars age is the reason for the issue , not sure if they are aware that hijacking wouldn't be an issue in SA if this statement was true and services such as their's would not exist?! When you call they act like they always working on things and investigations are happening, yet you don't ever hear from them. Broken promises that a supervisor or technical department or management would be in contact. Let's not even get started on the fact they send out technicians to install a unit whom rely on Google to find out information about the installation during the installation process, and expect the person who did the installation to come back and rectify the problem all on his own with zero oversight. Even VESA was left with broken promises on a submission of reports. A car not functional is all I'm left with. Clearly no value for the client, no matter how many vehicles you have with them or how many years you have been with them. After reading hello Peter reviews I am dreading even going through the cancelation processes but I guess wish me luck.
