I canceled my business card shortly after they switched and the rep seemed to not grasp why I was canceling. I canceled my personal card last week and they completely understood and had a whole line of BS they were reading from a script that had clearly been designed to counter those of us canceling because of the devaluation. Unfortunately insulting your customer's intelligence by telling them that they're really better off getting 2/3 of what they were getting before isn't a great way to do business, not sure why incentive programs all seem to think it is, so I'm done with them if/until they come to their senses. Hopefully the fact they have a custom script for it now shows that we're hurting them enough for them to pay attention. That had to be a cash cow for AMEX that will largely go away as everyone cuts spending if not canceling their card altogether.
I have had both personal and business for over 4 years, now I am not sure if they are worth keeping, but the free annual night still pays for the AF, for MS or daily spend, definitely not worth it.
