Pathetic service !!

Terrible service!!!! About a year back I gave cartrack an excellent review and they deserved it. But my most recent interaction with them has left me in shock and disgust. I had scheduled a de and re installation on and old vehicle to a new one . They took 2 weeks to respond my request . I had to call them to follow up . They then schedule a day for my installation confirming that they will do it on said day . I spend the entire day waiting for them to come in and install and they don't show up ( also I did call them at 11 that same day making sure a technician shows up ..scheduling even confirmed again a technician will be sent to me on that day . I try to call head office then they forward me to Durban branch.. Durban branch has no words for me when I'm on the call with them at 16:45 . They keep putting me on hold till 17:00 (their closing time) and then disappear.. no call the next day ..nothing .. a technician calls me at 10.30 the next day to check if I'm available.. which I was then he installed. As a customer my time is the most valuable thing to me . Cartrack has seem to have lost the plot and asoon as my 36 months are up .. which is soon.. I'm definitely going to look for a service provider that can cater to my needs .
