I hate that actually. I don't know if there will be a day in the future when an AI agent will be indistinguishable from a human being and therefore able to solve what you want just as well or better, but at the moment these bots are a waste of time and all they do in most cases is waste your time, as you say, until they pass you on to a human.
Also, a chat-bot created to consume leads or escalate queries is not really an AI agent if it can't take actions as a human would. The goal is to have the human chatters replaced with AI Agents which will be more efficient and cost-effective.
