Bots are great for FAQ kind of stuff and you don't have to wait on the phone for "the next available representative" and listening to the answering service continually proclaiming "your call is important to us."
Use your judgement as to whether you should be working with a bot or a human. Conflating matters, some bats are backed by humans. If there are things they don't know they'll ping a human to provide an answer. Not all bots are like that though.
