Taking money but no service

I bought a new car and phoned King price to change my old car to the new car details. I was told that I need to fit a tracking device on my car for an extra cost of R59.00 per month. I was also told that king prize will phone me to arrange for the fitment and also that they won't pay if this isn't fitted to my car. After 2 weeks of getting my car I phoned to find out what is happening, and was told they are very busy someone will phone me. then a month later I phoned again and I was disconnected 5 times. I've send a message on their website to phone me. when the person phoned it was a consultant selling and not customer service. I was assisted by this person and then told that I must phone the tracking company. I then mentioned that I'm paying for the service why must I now phone if I was told they would phone me. This person phoned and also couldn't get through and said they will phone me back. No one phoned. again I phoned and was told they will get back to me. I've been paying for this service now for 3 months and yet no one bothered to phone me. One lady from King Prize send a mail also saying they must phone me and yet nothing. this is really not on.
