Dotsure is not addressing my Netstar problem of being double charged!

I once again yesterday reported yet another complaint to Dotsure regarding Netstar who have been billing me separately when the tracking fee is already included in my monthly premium with Dotsure. This means I am paying twice for the same tracking device. I have been having endless problems with Netstar, and mind you, you are forced to take out a contract with Netstar if you want to insure your vehicle with Dotsure. My previous tracking company gave me no problems whatsoever, and my previous insurer did not force me to take on a contract with a specific tracking company, and I was free to choose whichever tracking company I prefer. Now Netstar is harassing me on a daily basis demanding I pay them around R340 of fees in arrears. How can I be in arrears if the Netstar fee is already included in my monthly premium which has been paid without interruption since I joined Dotsure last year?? This is a violation of my consumer rights and Dotsure has not done anything to resolve this mess!
