nsurance Cancellation and Refund

I have been incorrectly charged for insurance. I took our RCP on 16 August and cancelled the insurance when the monies was released in my account on 19 August (visited the Sandton branch). I also spoke to Beauty on 27 August at 11:18 to confirm my insurance was cancelled and yet I am still being charged. I spoke to Phumi 26 September and she requested I attach my statement and send an email for refund (per refer to original email sent 27 September from ***). Furthermore I have contacted the call centre and emailed on numerous attempts with no answers being provided as yet.
