Bank charges not seen by call centre against charged on my credit account

I have a credit card with Woolworths and every month I am being charged bank charges. I called the Woolworths Financial Services department call centre to enquire about the charges charged on my account the lady on the phone said she could not see the the charges I was talking about. How can I be sent a statement every month showing the breakdown of the amounts charged bur the call center agent could not see what the amounts I was talking about?

I need someone to sort this matter or I am going to take legal actions against Woolworths. The agents are rude and do not want to help. She was not helpful in any way.

I pay every month my installment but the balance is not going down.

I have been a loyal client of Woolworths for years and this treatment I am receiving is not what I had expected.
