American Express, meanwhile, has offered a brief note of concern for my well-being, and a vague promise of assistance as needed. If that help is needed, I should just call, visit their website, or tweet at them. I should definitely not, however, email them, as that would obviously be a ridiculous way to communicate.
Is it ever reasonable to send a customer an e-mail that specifically says not to reply? I’ve always been told, but not really believed, that financial companies don’t like to communicate via e-mail out of security/privacy concerns. But what could be more private than a tweet?
