I have scheduled a de/re for a tracker to be moved to my vehicle to avoid having to start a new contract with cartrack. It's been 3 months now and no deinstallation has been done instead theire technician is calling to make a schedule to install a new device. Mind you, I have already paid for a de/re. When I make calls to get it sorted my calls are being moved from client services to scheduling and to account for refund. Worst service ever, wouldn't recommend anyone to do bussiness with this guys.
