Poor repeated service from Nedbank Century City

More than 4 weeks ago i reported potential ***** on my credit card. I went back to the Century City branch to find out whats happening because Nedbank did not phone me as promised. After waiting for an hour there was no progress. The lady could not even give me a reference number for my enquiry. Real bad service from one of the biggest banks in SA, and who makes a customer wait for an hour for progress on a call already logged.
