Amex Centurion cards.

I was "upgraded" from Amex Platinum to their Centurion card, which is supposedly "THE CARD" globally. The fee is the highest of any credit/ debit cards and the service is the worst. IN THREE YEARS HAVE NOT HAD ON GOOD EXPERIENCE WITH THEM and I think Amex is doing their business i disservice to allow Nedbank to run this card the way they do.
