Nedbank lack of product knowledge... Saddening

The nedbank app seems to be dead weight on my phones RAM... NEDBANK has removed my message functionality and that leaves me with a account that I can not do transfers or payments from... Reached out to a nedbank consultant and their solution was that I use the card number instead of the linked account number that was set up by nedbank and has worked before, was still bussy talking to the consultant when they basically just cut my chat with them... I'm not sure if it's a lack training or knowledge of their product, which I could rate it a zero star... Such a inconvenience
