I hate it when companies force me to speaking/chatting with bots and makes it very difficult and time consuming to get to a human.  I get angry and i wish i have enough power to make the company bankrupt and punish the CEO.

Same. If I'm contacting support, then a bot is unlikely to help me. I know how to read an FAQ page.

The only bot that I've found helpful is the amazon bot. They actually give it the authority to reorder items you didnt get or were damaged or whatever. So that's interesting.
