This has reached new heights when calling USCIS for immigration issues. You have to avoid certain trigger words or the callbot will shunt you into a loop that can only terminate with it sending you an email on how to do something on the website, then hanging up. If you say "operator" it will go on a spiel about how helpful it is and you should ask it a question. If you say "operator" again it will hang up on you. The only way to get to a human is to look in online forums where people share the magic phrases that get it to direct you to an operator. Most of these have followup comments saying "no longer working as of $date". The US government basically hates immigrants or anyone trying to help immigrants and is happy to make things as aggressively unpleasant as possible for them. It isn't a bug, it is intentional.
