Debiting my account without authorization

On 18 November, Nedbank debited my account for R723.31, I called into the contact center and the cheque account department, who advised that I should call in next day to reverse as nothing had reflected their side. I did just that, to only be informed that it was Nedbank who had debited my account, via their legal department for a credit card that had now been passed onto their legal team. <br> Firstly as per my ITC report, my credit card with Nedbank had been written off...I have the proof if needed. Should this have been reactivated, why was their no communication, no phone calls, no emails NOTHING to inform me, and if there had been I would have made an arrangement. How dare you just take out of my account without any communication AND for this amount money, as far as I am aware, banks are suppose to help people. This is not the first time that I have had an issue with Nedbank...this bank is pathetic and I want my money reversed, I WANT someone to contact me to make PROPER arrangements, I WANT a statement for the payments I will be making and I WANT all my accounts with Nedbank closed and confirmation thereof.
