Worst service

Nedbank has the worst service ever. I collected my credit card at Clearwater mall on Saturday the 29th of June and had used the card fine until Tuesday the 2nd of July when I went to the petrol station. And tried to pay for petrol and my card was declined. When I called the call center the same day I was told I needed to do FICA then after 24 hrs my card will work again. I then went to the Rivonia branch the same Tuesday did the FICA but my card hasn't worked till today. I was sent from pillar to post between the nedbank Rivonia branch and the credit card division no one knew how to remove the Status that has been put on the card. Yesterday Friday the 5th went to nedbank branch at Flora center were the consultants were very helpful they helped me call the card division where I was transferred from one department to another, eventually ended at collections department where the said I needed to email my bank statement again in order for them to assist, which the consultant at the flora branch did. I had not received an sms or even a phone call confirming that they had received my documents. What is the point of having a credit card that you can't use and why it has to be my problem that your staff didn't do their work correctly. Why wasn't I contacted about this before you actually put my card on hold.
