Cam

Cartrack installed a new tracking device and a cam in my car early this year, around January. The tracking device is working but the cam has never worked, but R89 for the cam goes off every month. They called me twice around February for an appointment to fix it, till to date, no one has ever came. Basically I'm paying for nothing. I want them to come take their cam, I'm told that there's a cancelation fee, how do I pay a cancelation fee for something that never worked? All I want is for them to come fetch their cam...
