Nedbank do not care about their clients as long as they can take their money

I have experienced a bank that is so unsupportive. I app**** for replacement debit and credit cards two weeks ago on the 1st of April at the Branch in Kenilworth Centre. I was told it takes 3 to 5 working days. I waited and on Friday 9th I contacted the Bank and was told that no one ordered the cards for me. I asked to be put through to the complaints department. They promised me the matter is going to be escalated and I will be contacted by the manager of the complaints department within 24 hours. Nothing happened. I phoned this morning 15 April at 10 am. They then only app**** for my cards and told me it will be forwarded in 3 to 5 working days. I phoned the complaints department and was told that the manager will call me back within a few minutes. Nobody phoned. Are they really so inconsiderate. I feel like taking my business to another bank. I have all my various accounts with Nedbank and this is the first time I am experiencing such bad services.
