Disgusting Service

I have an American Express Credit card for more than 25 years with Ned Bank , I needed to use my card recently and discovered that my card was blocked due to not being updated which is totally acceptable as I fully understand that according to FICA it’s a regulatory requirement . My irritation is that I was not contacted via sms , email or even a telephone call to advise me thereof yet you still want to charge me a monthly fee for the card yet you do not allow the use of your product . I have tried to contact Card Division without any success . After more than 25 years , I will close my account as my loyalty is not appreciated by a bank thats unprofessional and inefficient .
