Policy against my name i did not apply for

In may 2015 I cancelled my Netstar Sleuth product, and asked for immediate cancellation. Received confirmation that it will be done. My bank account kept on being debited by Netstar, and when i eventually got feedback it was to tell me that the Netstar Sleuth has been cancelled, but what is being debited from my account is a value add: Road Protect. What?? Inception date was in May of 2015 - apparently. Same month i cancelled my Netstar account? Something is fishy. My account used to be debited with R115, then after cancellation of my sleuth, i still continued to pay R95 - so my sleuth apparently only cost R20 per month, and R95 i paid for something i did not buy. I again phoned Netstar Value Add department in September to cancel the policy and to refund me for all the months. My query was logged. Or so they said. Nothing happened. I again got debited end September. I phoned again, this time to be told that the initial query was never logged, and that it will be logged now. I am still waiting for my refund, i am still waiting for feedback. And apparently there is NO ONE else i can speak to at road protect expect for Kgomotso Ramono, and she is never available.
