Unfortunately, my impression is that human customer support often works just as well as a current-generation chatbot: They'll tell you what you want to hear, because they get rated by customer satisfaction. You get the survey, indicate that your request was resolved to your satisfaction, the agent gets their bonus... and a week later you realize everything you have been told was a lie.

This got so bad that when a customer support agent at Amazon genuinely resolved my issue well once, I was surprised that it actually worked out as promised.
