Yeah, when I sense that (B) or (C) is coming up, I stop the person cold and I demand to know the direct-dial number for wherever they are transferring me. And these days I also ask to know the department name as well, so I can figure it out if presented with a tree or org chart or something. It doesn't always help, but it helps me feel a little more secure.
A) Nobody is available to take your call. Press 1 to leave a voicemail. Mailbox full. Click.
B) A human answers. They're not the right person, but can transfer you to the right person. Click.
C) Same as B, but after they transfer you you're told 'Mailbox full. Click.'.
D) Same as B, but they transfer you to the top of the phone tree.
