Extremely poor client service!

If it were possible, I would give CarTrack 0 for client service. I have had three appointments booked and confirmed for the fitment of a dashcam, all with no-shows. What is worse, there was no communication from the company each time. Today is scheduled appointment #4 and I have (at least) had a call to notify me that the technician allocated to my installation has called in ill - this was also the excuse for the previous no-show. So what does it take to get any service? And in the event of my vehicle being ****** or hijacked, is this the level of service I should expect from the company? Totally unexceptable.
