Yeah, far too many systems try to cover every case in the menu and deny access to a human--but never have I seen one that actually covered anything like every case. They cover the easy stuff and you have to get hostile with the robot over anything else.

Or our local pharmacy--it has it's own number but if you actually need a human you're dumped into the general phone tree and have to go back to the pharmacy and persuade the robot to let you through to a human. And the designers never put things in the menu for the stuff that needs a human.
