Actually, the recording from Prime Mail pharmacy provided an unlisted number for me to call back to.  It is a direct line to their pharmacist at pharmacy.   They wanted to tell me of a problem with filling the order and needed me to double check with doctor or something.  The problem is they do not leave a message on my answering service.  In their messaging  system, I had to click or say some words of confirmation that I am the person named that they are calling.   And if I do not have a pen ready, their odd ball long distance number is bye bye, who can remember it.

So while legit, it is an unsatisfactory system.
