In December 2022 I had to switch from my current account to a new account due to my account phasing out and was promised certain things. Never received. And in February I made an immediate payment from my account to a supplier. They only received the funds 24 hours later. I lodge a complaint and received a call back. After the caller failed to get me authenticated she promised a call back the next day and her call was just to inform me that they received my complaint. To date no refund or call back or any promises has been kept. Standard bank your service is atrocious.
