Money debited from my account *******LY without my permission

I have been with Nedbank as a client for more than 10 years. I reported an issue on the 26th April where an amount of R7598 was debited from my account without my permission. It is now the 08 May and still has not resolved - I have escalated this issue and spoken to 4 different people.

I did my research and I am aware that what they have done is *******. Credit providers may NOT deduct money from any of your accounts. It was declared in a judgment between the National Credit Regulator and Standard Bank handed down in June 2019 that common law "set-off," as it is known, is ********.

Even if the contract or credit agreement included such permission, it is still not lawful. No one may deduct funds from your bank accounts unless you have signed or given written consent for a debit order for a specific deduction from a particular account adequately identified.

I am a Private Client - I am disgusted and I will be taking this further.
