Chatbots

Personally I hate chatbots. One more incident today. I had to explain about an issue 4 times from the start. Because every time the bot couldn't understand the issue and was closing the query. How do the companies measure the success of these chatbots. Certain that the success rate is quite low. Barring only the cost issue I don't think chatbots really helps the company, also to the customer. I will prefer a brand i can talk to on a call(please not a robocall) and just the end issue at the first moment. Service companies should definitely look into the customer satisfaction index.
