Absolute Zero score for Tracker service!!

As requested by my insurers , we needed to have a tracking device installed in our recently purchased Ford Everest. Fitment time was schedule was scheduled for Friday 26 April. Despite the agreed , and confirmed time , the installer arrived 1 1/2 hours early. The installer was supposedly an "approved" installer for Tracker and another tracing company. After an hour's work I was called to come and sign the necessary acceptance documentation. I requested a demo , which was not possible according to the installer, as the vehicle was next to an electric fence. I moved the vehicle into the street and still no demo possible as the installer's tablet was not functional. I was advised to download the app and perform the test myself. I was gob-smacked at the reply . The installer then phoned his boss who promptly advised me that if I am not happy with the (non operational) system they would immediately proceed to remove the system. There was absolutely no way that I was going to allow a technician allow entry close to the vehicle wiring, armed with a pair of side cutter in hand. By now the debate between us became heated and I told him to leave. Despite not having signed anything , I received two accounts from Tracker later the same afternoon. Thereafter , every time I start the vehicle I receive a message from Tracker wanting to confirm that I was safe , If not I needed to phone their call centre. Tracker in turn phoned me twice advising me to hold on for the next available operator. I hung up on the first call after 15 minutes , the second after 10. The long and short is that I now theoretically conform to the requirements of my insurer but should I need a tracking system due to danger , I would be the proverbial dead duck! I suppose this is what happens when companies become too big - and too big for their shoes. Shame on you Tracker!!
