I find customer support service Chatbots useful, they tend to ask the right questions before connecting me to an actual human, so I don’t have to explain myself over and over. They also categorize your problem so you won’t be forwarded 3 times till you finally reach the right department. They’re essentially like the “press 1 to…, press 2 to…” shtick during a service call, except the customer support person has access to your chat history.
