I've definitely experienced the first half of the story: banks really will do dumb things like this and then be surprised when someone is upset by it (anti-fraud protection tends to be the worst: a text-message from a random unaffiliated number with another unaffiliated number to call, where you must then provide account details in order to get your card unblocked, and trying to call the official number and go through the phone tree does in fact, eventually, tell you that it was legitimate, but only after hours of being batted between departments).
