Well, the same happens for chat text interfaces, but I have used those much fewer times.
People usually don't call the normal usable UI that solves problems "automated customer support", but if you refer to a navigable web site with real options to solving things, then well, you are offtopic but that one works.
It's not offtopic. Many people in this thread seem to think that any customer service UI that's powered by AI/LLMs has to present a chat/voice interface.
Well, where else do you plan on using the AI? On search? (Yes, it would be an improvement, but search is not very far from chat.)
Automated customer service works exceptionally well if it's done with care and doesn't involve AIs. But we simply do not have any AI design that helps with it. All designs we have only hinder it.
