Refund still not reflecting

On the 22nd of June 2015 I requested my broker to cancel my liability insurance with Santam. I tried to do this myself, but was told i needed to go through my broker. The premium was deducted again at the beginning of July 2015, and since then I have been requesting the refund through my broker. I am told at least once a week that he has been promised a refund on that day, but to date this still does not reflect in my account. Please can you shed some light on this. We changed all our short term insurances in June and all the other insurance companies have refunded us - whats up Santam.
