Express Scripts is so hard to work with. First off it should not be a 20-minute frustrating experience to get a live human on the phone! Now onto the whole experience. This is the absolute worst pharmacy I have ever had to deal with. I am now on year two of this crap customer service as this is the insurance my employer forces us to use. If you need a medication urgently you are out of luck! It take forever to get medication from them Several times I have paid full price for medication because I cantr wait for them to fill them. Second is the lengthy process of getting preauthorization done on medications you have been taking for years! I have now been without a much-needed medication for two weeks and still no resolve. My wife needs a medication that is on backorder, there is an alternate but they will not approve that either!! I am at my wit's end with this company!!! PEOPLE NEED MEDS!!
