Poor service

I bought a new vehicle and called cartrack to remove the tracking device from the old vehicle and install it on the new vehicle. They said it would cost R870 which I paid immediately and I was informed that a branch will call me to arrange the reinstall. 4 days later I called them and they transferred me to a branch. The person who deals with booking of technicians was not at the office around 10 AM and after 2PM her line was busy. After lodging a formal complaint with the office of the ceo only then did somebody call me on day 5 after paying for the service.
