Just want to get a device for my new car and cancel the old one!!

For the past 3 or so weeks I've been trying to cancel my tracking service as I have sold the car. I would like to put a new tracking device in my new car.

Despite numerous calls to them, cancelled appointments by their fitment centre in Somerset West with the new owner of my old car and promises that someone will call me to arrange an appointment to install new device in my new car, this has not been resolved. There just isn't any communication from Matrix!

What is going on with my request?!?!

Im at the point that i feel that my only option is to cancel my tracking services for all 3 of my cars, pay whatever fee they want me to pay to terminate and go to the competition instead! This cant be the right outcome

All i want is a tracking service for my new car and not to pay for the car I've sold: Is this to much to ask for?!
