Bad service by cartrack

I feel ****** by car track, I had 2 vehicles which were under car track, 1 vehicle got in a accident and written off by the insurance in October lasth year, and it had a camera from car track, I asked them to remove the camera n install it to the vehicle that is still driving, and I struggled with that n I have been calling them and they have been telling me that the camera went for repairs, which was a lie, all along the camera was with the technician who removed it from the written off vehicle, I went to Durbanville cartracker office n I was informed that the camera is on its way from Jhb, I then asked for the technician who removed it then he said the camera has been with him all along, the receptionist informed him to bring it to the office, and she said I should pay R600 for De-installation and Re-installation, which I didn't have a problem with, then an appointment was done for the technician to come after I paid the R600 and the technician didn't arrive, I called him the following day and he said the cameras are out of stock, I then reversed my R600 as I felt like I am being fooled n **** to once again, I told them that I will continue with the monthly inspection of the camera I do not want their camera, I won't pay the R600 as they are having their camera, now I see that they have debited R552, R492 and another R552 and when I ask them the reason they say that it's for the camera after I had told them that they must keep their camera I will pay the monthly subscription which is R492, that includes my tracking unit and for the camera monthly subscription, they have been lying to me I have been paying for a camera that is with them n now they are debiting money for re installation which I do not want n they are having all the recording of the phone calls they can listen to them n they will clearly hear me saying I do not want their camera n I don't Want to pay the R600 for the camera which they **** to me off
