On August 30, 2021 I received an email from ExpressScripts that they were processing 3 of my prescriptions. On September 17, I received 2 of those prescriptions. When I called to ask why I had not received the third prescription I as told that there was no active third prescription. I advised the person on the line that I had an email from ExpressScripts listing all three active prescriptions. I was advised that they could not locate that email and that only two of the prescriptions were active. I advised them that it was fine if they needed to reach out to my doctor to confirm the third prescription, though it seemed ridiculous. When asked what shipping method I wanted I advised that I thought they should send it same day delivery for free, as this is a medication that causes serious withdrawals. I was basically told they couldn't do that. I felt that there was absolutely no responsibility taken for this mess up and whenever I tried to ask questions about what happened to the third prescription I was never given a clear answer. This was the absolute worst customer service experience I've ever had. At this point I'd rather pay full price for my prescriptions then use ExpressScripts through my insurance.
