Unauthorized Debit Order

I am utterly disappointed in your company as I called in twice in February before the commencement date ( 01 March) of my life cover to cancel it . To my surprise the debit order of R536 has gone off from my bank account today. I want that money to be paid back into my account IMMEDIATELY as I told the consultants on the phone I couldn't afford the life cover and that was the reason for cancellation. They assured me that the calls were recorded and that the policy was cancelled.
