Unauthorized third party debit order

Disgusted,Nedbank is *****ing my money.

Last month they allowed a debit order from an attorney to go through on my account for 7k.with no authority to debit my account this is even a account number they this is *******.i had to wait 7 days before my money was reversed I was assured this will not happen again I have another debit on Monday and another debit today. I am completely frustrated I want my money refunded immediately and I will be closing my account.Can some one please email me on *** as I don't want to be forced to go to social media also.
