Bad service from Cartrack

I had a few cameras fitted to my vehicles, I lodged a fault with the Cartrack scheduling department on the 11/03/2026 about the camera falling off and had to be refitted. I recieved sms/ watsapp messages confirming that the the technician will go out on the 12/03/2026 reference *** at 8 am. I called their scheduling department ,answered all their verifying questions. The guy then tells me that they do not have stock on the camera and thats why their technician Shane could not go out and do the job, My daughter waited at her work and didnt go expecting cartrack to pop by. I was not called and informed that they could not do the repair today. However they were prepared to do it yesterday and I out of consideration due to the time agreed that the 12/03/2026 would be better. If I had called in to enquire , my daughter would have waited in vain due to this unproffessional service. I cannot wait wait for this contract to end and move my business elsewhere.
