It's extremely frustrating to have a real issue, take for instance a plane cancelled or delayed when travelling with kids, and not being able to talk to a real person who can actually help. Let alone having to wait 30-60 minutes to get a hold of someone.
Nowadays most large organisations are structured now that it's impossible to have a conversation with a human who actually has the power to make a decision. All they repeat is info that's found online and tell you to fill in a form or email.
In that case a chatbot is probably better for both sides, mainly for the person behind the phone who doesn't get verbally abused on a regular basis.
Sadly best way to get helped by corps nowadays is to tweet to them.
