Nedbank need to "See service differently"

I opened a new account with Nedbank and have been terribly disappointed with their service at every stage. I have been waiting for 3 weeks for my cards to be delivered. No communication at all. I have debit orders to organise before the 25th and this company can't get cards to me in three weeks. Ridiculous. Their app is the worst banking app I have ever come across. Keeps disconnecting when speaking to a consultant and then I have to repeat the same query with different people. Frustratingly poor service, none of the consultant get back to you to update on progress or rather lack thereof. Biggest mistake moving to Nedbank. All excuses and no solutions. Biggest mistake moving my salary to this bank.
