Cartrack Customer Service is bad

Once you are a client then they don't worry anymore. I bought a new car and now I'm struggling to get Cartrack to get the tracking unit removed from the vehicle that I've sold and to get it installed in the new vehicle. Now I have to pay for service which I can't even use. Every time that you phone you have to hold on for very long and they keep on moving the dates out on the availability of the technicians. No one wants to make effort to resolve this. This is very frustrating.
