Today in chatbot uselessness: I was looking for a sentence I knew existed in my bank's website, explaining the procedure for one very specific action. The bank refuses to receive email and does not have a search function; both have been replaced by a chatbot. The bot insisted I must have misspelled my question, and kept directing me to a completely irrelevant page.
Luckily, back in 2014 I saved a PDF file which contained the answer. Once I looked it up, ctrl-f solved my problem in a minute.
