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...
