Blocked card and no Replacement

I had to replace my bank card last week due to the consultant telling me that the chip on my card is faulty which is why I need to put my pin in 4 times until it is accepted. Sunday the bank blocked my car, giving me no access to money and my card being declined at the shop. I called today and I kept being told DSV will deliver the card, but its been days. DSV then sends an email today sying they are unale to deliver the card and I must contact the bank. How can Nedbank let this happen. Now I have no delivery of my card on the way and I am sitting with a blocked card inable to access my account or use the card for online purchases. I do not seem to be winning. I have called 3 times today, the line either goes dead or I get told it will be sorted and nothing is happening. Seriously frustrated.
