Cartrack keep on debited our account

We have been with cartrack several years but due to them not answering phones, you have to pass up to 4 operators before you get helped. They do not understand our situation. The device was in my wife's name and we inform them several times that I will use the vehicle. So when we bought a new vehicle and opted for Netstar which is actually brilliant. Now Cartrack keep on debited our account every month, notwithstanding that we asked them to stop it. There operators are arrogant and very unfriendly. Never consider CARTRACK please
