"All our agents are assisting other callers"

We get most of our meds by mail.  That means that every now and then, I need to contact my nurse practitioner to fix a problem.  Today is Monday so 9 AM is probably one of the busiest days to communicate with a medical professional.  My phone said I waited on hold for 30 minutes for a human.  That is the longest I have had the stick-to-it-ness to wait.  During that time, about once every half minute, I get a recording of a nice lady informing me that everyone is tending to other callers.  The system has probably been informed that I am a grouch and can be left to the bottom of the list.  Well, it seems that way to me.  The nice lady seems to think I may not be listening carefully and as minutes click by, she is correct.  So, she repeats herself twice every time.

I admit the system offered me the option of having it call back when someone was free but I didn't accept.
