NO RESPONSE ON REFUND & CANCELLATION

I took out insurance with Oaksure on 14 July 2015. I was never informed that there would be a broker's fee of R750, the only amounts confirmed were the premium and pro-rata amounts which I agreed that they can be debited on the 25th of each month. On 21 July, I was debited R750, I phoned & was told that the amount is the brokers fee. I was then informed that I would get the money back within 7-14 working days as they had listened to the tapes of my conversation with the broker & can hear that I was never informed about the brokers fee. 14 Working days have passed and I still don't have my R750 back. I've been phoning & get told that a broker will phone me back & that my message has been passed on. On 11 Aug, I then asked that my policy be cancelled & was told that Ronald would phone me back & still nothing. On the morning of 12 Aug I phoned again & was told that someone will phone me back. Im still waiting to hear when I will get my refund & if the policy has been cancelled.
