I am a cartrack existing customer with two vehicles tracked by them and I wanted to add a third one. Service was terrible , poor communication and it’s not the first time iv experienced such . Even when I wanted to track my second vehicle, it was a mission. I am even serious considering moving my other vehicles to other tracking company because wow the service was terrible ended up cancelling the installation of the third vehicle and chose other tracking company.
