Chat bots are, IMNSHO, anti-customer service: a way to keep the customers placated "something is happening with my problem" so that the call center isn't overwhelmed (in other words, "woo, cheaper call center for company!")

I mean regular call centers employed that tactic too. Use the right language to make it appear as if something is happening, and you agree with the customer, but not doing either of those things.
