They give you the run around, denying your medications for retail pharmacy, then they take weeks to resolve before you can get mail order meds initiated. My doctor spent hours along with myself escalating various issues before we could get my meds filled. I was forced without medication for weeks. They claim they sent notification via email regarding my retail benefits that I never received. I have been on this routine medication for over a year and every month is a struggle getting it filled with Express Scripts.
