Cancellation request not done

I phoned iwyze on the 30 of june 2015 at 2:30 to cancel my insurance by the 24 of july 2015. I spoke to Siza Ngubane who confirmed that a debit wont go through on the 25 of july and promise to send me a cancellation confirmation letter which I still havent received. I phoned back the 22nd of july spoke to mpho from retention who told me my policy cancellation is on the 25 of august andvthe debit will go through on the 25th of july which is unacceptable. Siza told me her name means help clearly knows nothing of doing the first thing right and listerningvto what I was requesting her to do. I want the cancellation done and confirmed as promised and the debit order reversed. Im sad I feel im being punished for cancelling with iwyze. ***
