Tracker not responding or assisting

Hi on 31 October the Tracker Technician was here to install a new system on our Ford EcoSport. He was working on it for more than an hour. But left saying everything was now working. I downloaded the app and it showed that the vehicle was still standing at the address it was install. Which was not correct as it was standing at a different location at the time. I phone Tracker and they said it would need to be re-set from their side which they apparently did (according to them). I have tried on a daily basis to get it sorted out as it is still not showing where the vehicle is currently standing but shows the address it was installed at. Have spoken to numerous people including Technical Dept and they suggested a Technician come out to look. It's a week later and no Technician has been to look at it nor has the problem been solved. I did request a Supervisor phone me to discuss but this has not happened either. I'm very concerned because if the vehicle gets ****** we have no way of finding it and Tracker do not seem to be worried or interested to help...
