Limit increase woes

On the 9th of November 2022, I phoned into the Nedbank Call Centre, and app**** for a limit increase on my credit card. I emailed the documents required directly through to the person helping me, and she confirmed that she received the documents on email. She informed me that it would take 3 - 5 working days. I left the application for the period. But the 5 working days is long gone, and still no feedback, no joy in phoning into the call centre. I phoned 3 times today, spoke to 3 different people, and still I don't have an answer, and I'm still in the dark with regards to the application.
