Poor service

I am very disappointed with the service from Cartrack. Just recently bought a new car and request their service for installation of a tracker but I was never assisted. I called them in beginning of Jan 2025 and I was booked for 31 Jan for installation. On the day booked for the installation, the technician did not pitch and was not answering his phone. I then called Cartrack to inform them of this situation but they also couldn't help me instead they told me that they also can get hold of the technician. They suggested that I get booked for another day. So the date I was given is in 2 weeks time, of which means I will be driving without a tracker while waiting for them. I am now thinking of getting another service provider who takes their job more seriously. If it's so difficult to install how much more to discover my car if ******?
