I was promised that they will install a unit on saturday

I was promised that they will install a unit on saturday. They confirmed the appointment for 08:00 saturday and I was given a run around when I called them asking where is the technician at 09:00. The 1st technician was said to be booked off since thursday and I was allocated another technician. My application was done on thursday. The second technician's car broke. This was now after 12 wgen I called them. Then I was allocated another one. Who never pitched. When I call the customer service. Now, they are not sure if tge techs will be working on sunday. Sinday I see a missed call, I vall them back 10min later, the customer care agent says she is not sure if scheduling people are working but she will make sure I am attended to 1st thing in the morning. At 9:00 on monday, I call the schrduling people and they say my appointment is not not scheduled but they will schedule it today. To say I am disgusted of the service I received from cartrack is an understatement!
