It's great when it works. Yesterday I needed to contact support for a company but all they had was a chatbot. I explained what information I was looking for and it linked me something completely irrelevant and asked if this solved my problem - with big buttons to reply yes/no. I pressed "no" which simply caused a message with "no" to be sent from me in the chat. The bot replied with "You're welcome!". I wrote a manual clarification that this did not solve my issue. The bot answered "You're welcome". Luckily, I found that ignoring this and asking the question again did work.
