I really appreciate my medium sized ISP, which actually answers support emails in a timely, competent and helpful manner.

I don't even bother with bigger tech companies, including Valve. Getting completely senseless automated and canned responses just makes my blood boil and certainly doesn't resolve anything.

Another pet peevee are automated A (not very) I chat bots.

If you want to have a truly horrendous experience try Air Asia's automated customer "support".
