I have yet to encounter a phone system that refuses to provide a human, at least within business hours. But I've encountered those online, definitely, that aggressively want to hide any way to reach a person for something that you know in advance will be outside their script.

This one rings until it's about to go to voicemail, and then all of a sudden a fake dial tone starts and an AI agent picks up. I've only encountered this type for small business owners, like dentist offices and lawyers. But it doesn't seem like there is a way to reach the actual person. I could be wrong though.

I've hit phone trees with no path to a human. Haven't gotten stuck on an AI yet, but I'm sure it will happen. The AIs never have the ability to resolve the odd cases.

Jetblue wouldn't let me talk to a human unless I agreed to pay $25.
