Cartrack installation non existent.

I recently app**** for a cartrack device for my vehicles, as an insurance requirement. I selected Cartrack because it was the first company to come up in google. I was conatcted promptly by the company and we agreed to their R99 per month plan. I was promised a call from an installer for the same day. The first caller could not make it and pushed the request back to the Cartrack scheduling department. I received another call and a tine of 15:00 was agreed to. The installer did not pitch. I called client services and was informed that the installation was scheduled for 15:00 the following day and that the installer would call to confirm. At 14:45 I called Cartrack to confirm the installation as I had received no call. I was informed it had not been allocated and that they had between 10am and 16:00 to call me. I could not arrange a specific time to install. However they state clearly in their agreement that I will be charged an additional fee if I am do not make a meeting!!! They do not feel that they have to hold themselves to the same standard. They do not care that I might have prior engagements that require an appointment being made and kept by them. They also make excuses that it is a dynamic system (Or something like that) I was finally contacted by an installer at 15:55. To be informed he is 20 minutes away and that the job will take 1:30 hours!!! Impossible for me to accept the installation. It will now be pushed back to a scheduling department that clearly sates they do NOT schedule an installation. In the meantime my car is not covered because it requires a tracking device. They missed 2 appointments and refuse to prioritize. Does that not mean when I require them to find my car that they will have to schedule it between 10am and 16:00 and only at their own convenience???
