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.
The Bot offered to restart my DSL from their end and I assume the profile gets updated along the way there as well. So after a few minutes Internet was running at the desired speed again.
But I agree. Most of the Chatbots and Phone robots are useless to the point of directing you to the right department - asking for your authentication verification data for on-call support and then forwarding you to a Support Guy after 30 Minutes of waiting in the Queue. And even then in most cases you need to proof the same Auth data to the Support Guy again...
People seem all caught up in the new hottness, and forget the technologies that still work and are simple as dirt.
