Case Number ***0

My American Express card was stopped last year November after I collected it at Nedbank Mall of Africa. I called to check who stopped my card and none of your call centre agents are able to see who stopped my card. i even went to the branch and I keep getting the same answer that they can't see who stopped my card. A case was opened to investigate this and it was closed without being resolved and I never got any feedback. The case number in question is ***0. Please issue me with a new American Express Card and waive the charges. I will not pay R170 for a card that I did not stop. This is not my problem, it's the bank's problem. Please resolve this matter urgently. I have been patient for a year now. The card number in question is ***19058.
