Terrible Service from American Express Rewards

I app**** for a Rewards Card as my old card Expired, when i tried to activate the New Card which i collected from a Nedbank Branch i was unable to do so. Got message that your card has been restricted. Went into the branch to see if i can be helped, a very helpful lady assisted and called Amex Rewards card, to find out what the problem was. A new card was issued but was registered on the system can you believe this? 1 month now and the issues is not resolved. if you think you can get though you in for a surprise, you will be out on hold for hours. Emails will get answerer in 7 to 21 days of you lucky. This is supposed to be a top 5 Bank.
