Will Capitec refund me?

A few monthsago I cancelled a Telkom debit order with a Capitec client care consultant. (Attempts to do it via Telkom had failed.) The consultant was working from home. She took the neccessary details and assured me that she had cancelled it with immediate effect. It was, however, not. I then went to Telkom physically again. (Same story as with Capitec). (a) What must I do to cancel the debit order? (b) will Capitec refund me the money which subsequently went off my account?
