There is not discussion that Amex is much better to deal with than any bank when stuck abroad. You can get a replacement card at any Amex office nearby, use local Amex etc... Speak with Amex in France.
The only exception (no system is perfect) is if you need to speak with the financial department about blocked card for financial reasons (spending limit or else). They work Mon-Fri. And if your card is blocked during the weekend you're stuck. They had mis-allocated a payment and no one could help...
