NETSTAR IGNORANCE

When I bought my car from the dealership in April a Netstar Neno devise was installed on the car, my current car insurance company stated that there will be no need for me to pay for my tracker as they cover the tracking costs, I then contacted Netstar and the told me that unfortunately the Neno device is not the one that is covered by the insurance and that they need to stop the device from their side and request for a new device to be installed, after weeks of waiting this eventually happened now since then my car battery is always flat because there are two tracking devices installed on the car, this is frustrating because when I need to use the car I need to be boosted first while the car is brand new. I called Netstar today and requested that they attend this matter ASAP, I was told that I will be called by today for a booking to have the technician check the installed device but yet nothing, on the other hand I'm told that I need to pay R500+ to get the device removed which I believe is daylight ******* bacause the technician should have picked up that one of their devices was already installed on the car and could have removed it before installing a new one. From all the tracking companies I've used in my life I deem this as the worst because with my previous car the cartrack company removed a tracking device at no extra charge. I need my compla6to be attended to ASAP please I am using my car on a daily basis and therefore need to travel a distance daily. I need this device removed before it damages my car.
