Standard Bank doesn't need consent to take your money but they need consent for any other ****

So due to high interest rates at standard bank for their cheque account, I decided not to use the account anymore. I have had issues with companies debiting my account after numerous attempts to stop the debits which resulted in a ridiculous overdraft of R3000 over the period of 2 months. Having 3 accounts at Standard bank, they decided to take the R3000 from my savings account. Then I get the following SMS "Standard Bank Personal Cheques - SAP (100022) has debited an amount from your transactional account, to reduce the overdue amount on your account. Kindly contact ********** 770" when I call I'm told the issue is resolved and the refund is rejected. By who? With who? All I got was a rude consultant at the credit department who refused to help me. Standard bank states that they have A LEGAL right to take peoples money without their consent and without notifying the customer. So I let the debit slide and I decide to close all my accounts, turns out the consultant at Cresta did not close my accounts. Standard Bank doesn't need consent to take my money but they want my signature to confirm cancelation of my accounts? How convenient. Not only do they have high rates, they also give poor to no service quite disappointed.

Expecting a call to confirm all 3 accounts have been closed.
