Unauthorized and unstoppable debit orders

This dumb company is busy going into people's account debiting our accounts, even when you reverse and block, next month they come with a different reference number and continues with their ******* debits and ****** Nedbank says there's nothing they can do to stop them. There is no mendate, but then how is the bank not able to stop these debit orders.

My colleagues and I have been reversing and stopping the debits and it costs money to stop and it costs money to reverse.

I have never had any contact with these financial institution, how did they get our banking details and names. POPIA ..... They are then violating our rights. They never asked permission nor did they receive any form of consent to go into our bank accounts.

I hope someone will investigate them and shut down that useless company, it's obvious that it exists to rob people.
