In all my years of coping with poor customer service in various walks of life, I have never had the misfortune of dealing with any company as unresponsive, unhelpful and, ultimately, as harmful to my health, as @ExpressScripts and, their subsidiary, Accredo. A summary follows: in late September, when my doctor prescribed an injection of Euflexxa, to lubricate an ailing right knee. Express Scripts, after a delay of more than a week, denied it, saying I first had to try an oral medication and phys therapy, even though I'd already done both.
