We have a chatbot on our marketing site but it says something like "I am a Bot. Once I ask you a couple of questions, I can connect you to a human. Is that ok ?".
i like that better than fighting with a bot to trigger an actual human getting online. However, a few short questions and connect to human sounds like a form and a submit button.
If the end result is getting to chat with a human, that's fine. But so many of these are just a different interface to search the FAQs, and the end result is to link to the FAQs. That's useless.
