Nedbank stinks

So my nedbank money app went haywire, I can see my Cheque and savings account fine, my credit and Amex card however show 0, even though there is a few thousand Rand in there... so off I go to the bank to collect renewed cards and try sort that out. Lady at the desk tell me my accounts have been closed. Now I’m livid. Who gave them permission to close my accounts with money in it. She says it’s from inactivity... but I transfer money into it every month... doesn’t make sense... then she calls the credit card department who says it’s because my card is expired... expired or not I should still be able to use the banking app with my account number... btw my card only expired 2019.... again not making sense... so I get told that I can go home they will order me new cards cos they are being put on hold... I go home, later I get a call saying that I need to call the card division myself cos they have security questions for me, so I call... I get put through the right division the lady is very nice but whoops... looks like my account isn’t closed... merely blocked. She needs to call the ***** division and I get put on hold. After a while it disconnects and I have to call again... so I call again and can’t get through to her, I speak to someone new, he says he won’t put me on hold this time but he will call me back after speaking to the ***** division... and I’m waiting.... and waiting... nada...... what the hell gives then permission to block my card or disconnect my internet banking without my permission??? To pick up a card from a branch they need so much paperwork it’s basically a marriage contract but they can block my account and chop and change without my say so as they please and now I’m being inconvenienced???? If you want to block my account you better also block the banking fees! Anything for a quick buck nedbank? And how about my airtime and pertrol spend to sort this out? Not impressed!
