Tracker is useless!

I app**** for a new Tracker device to be installed in my vehicle on 19 June 2025, it was approved. I requested installation to be done on 21 June 2025. They were going to call me to confirm an appointment. On Monday 23 June I still had no call so I called them. We confirmed an appointment on 25 June at 9H30. On this date nobody arrived, so I called them again. They said I made a mistake, the appointment is for today 26 June at 9H30. Nobody arrived. I spoke to them again just now, they said no my appointment is for 1H30 today. I complained and the consultant then said he escalated the matter because I am not happy.

I need to make this clear to Tracker, your devise is mandatory for my insurance. You can come when you want but be sure that if my vehicle is ****** and not paid by my insurance, I will keep you liable for the loss due to your incompetence.
