Terrible service no urgency especially on faulty devices

Unable to track the vehicle with accurate tracking information. Since installation I've been calling the Germiston branch. They said I should call Head office, done that last week. Was promised a technician will come out almost a week later , no action. It's very concerning that the device is not working properly especially the fact that I reported it several times. Can't believe this is the type of service we getting from Netstart
