I find them deeply upsetting, not one step above the phone robot on Vodafone support: "press 1 for internet problems" ... "press 2 to be transferred to a human representative". Only problem is going through like 7 steps until I can reach that human, then waiting some 30 minutes until the line is free.
But it's the only approach that gets anything done. Talking to a human.
Robots a a cruel joke on customers.
But it was almost the same before chatbots. You got a human, but it was a human that had a script, and didn't have authority to depart from it. You had to get that human to get to the end of their script (where they were allowed to actually think), or else you had to get them to transfer you to someone who could. It was almost exactly like a chatbot, except with humans.
