Most of your interactions will probably be answered by the bot, lowering your time of response to the minimum, but your customer might ask things to which the bot hasn’t been trained yet, or talk about a more difficult or delicate subject. In these cases, you’ll probably want to offload this user from the bot to an agent in your customer support. One good practice is to always offer this as a fallback from your bot and communicate it to the customer, asking if they want to talk to an agent.
