Not receiving my credit card

I was told that I qualified for a credit card and that it will be delivered to me last week. Today I got a call from the delivery company who will not accept any form of proof of address that I have. I phoned Nedbank, but they could not really help me. In the end I was promised that they will email me a letter that my fiance can complete that will serve as proof of payment. It's 4 hours later. Am I ever going to receive my credit card???
