I was dealing with a LLM help bot on a website where I had to upload some documents and asked the bot how to get through a step where I simply don't have the right things and it kept telling me I could sidestep that (but I could not) or upload the thing (which I told it I could not to begin with!).
It's not like the previous tree based bots were good but at least they had a path to speaking with a person.
I suspect nobody ever tried to use the bot.
I had a bot tell me to click something in the chat when it had sent me an email... The whole experience was so bad that the company behind it lost my business.
I've had the bot of a "modern" holiday home tell me some rubbish about luggage storage. Fortunately, I knew that there would be a human fallback during working hours so it worked out OK. But who thought that it was a good idea to have a shitty bot to ask about important things?
