Money debited from my account after receiving a quote. Please don't ask Momentum for quotes!

On Fri, 6 June, I called Momentum to cancel my building insurance policy. I was put through to a lady who canceled my policy but then assisted me with a quote for content, she was unable to beat my current service provider premium so I said I will get back to her. Last week Wed, 18 June, I look at my account and see an amount of R676 debited. I call Momentum only to find out that the quote I received for Home Content was actually debited from account. I spoke to a gentleman who promised to get back to me the next day after they listen to the call and promised that the entire amount will be refunded. It's been a week and no one has contacted me. Can someone please rectify this matter. I cannot believe from a quote, money is just debited from my account without my authorization.
