POOR SERVICE

We have a fleet of vehicles with cartack. I sold two vehicles wcich (had the tracker for almost 5 yrs) The lady Lucindilee has not at any point to told me when I told her that I have to cancel in order not to be billed. She kept saying that they will de-installation and re-installation when we have the new vehicles. The new vehicles could come in 6 to 1 yr time and I am still being billed for it. I'm told by her that billing cant be paused? So why was I not told this?If I knew this I would have cancelled . Now Almost a month later I am being sent a cancellation form. The installation team has not even de-installed these trackers yet even though they have been sold almost a month ago. Going to move our whole fleet to Netstar now.
