car track upset customer

zero review for this company. I currently have 2 vehicles with cartrack. recently sold the 1 vehicle and informed cartrack about this move. they advised that it will be best to remove the device from old car to new (i gave them the details). I have been waiting for this to happen since Jul. i'm still paying premium for the tracking unit. all they do is debit my account for the deinstallation and reinstallation of this tracking unit. they ghost call me harrassing me since i keep reversing this amount. i called these guys to follow up. they have no idea how and why the unit has not yet been reinstalled into my current vehicle. i'm truly ****ed off by this company. i now cannot use the tracking App for my other vehicle and they tell me i should pay the deinstallation fee for them to unlock the app. my argument is why do i have to pay these people when they have not removed the unit from the old vehicle. i feel ******. i hope the head office sees this because im done making contact with the call center those people are rude and useless. especially Nonhlahla who dropped the line in my ear.
