I received a computer generated call/recorded message from them. It said one of my prescriptions could not be filled, and rattled off the number before I knew I needed to write it down.
Then it said, "We will send you a letter."

WHAT? Why can't I talk to a person to figure out exactly which Rx you are rejecting and why? I can't wait 10 business days to get the letter from you. I need my meds.

Trying to call through on their 800# is useless. You'll go through a 3o minute phone tree and push a ton of buttons on your phone and still never talk to a human being.
