Hey guys, I chose to fill two prescriptions using the Express Scripts Mail order pharmacy in January. Ever since then, it has been nothing but problems. They overcharged me for both prescriptions, in one case by more than $100. They also sent me a prescription that I didn't even authorize and billed me for it. I have spoken to them more than 20 times, spoke to supervisors, was assured they will fix the issues, but they haven't. I filed a greivance with my medicare drug plan and they said they'd fix it within 30 days (according to their contract), but they haven't. I even disputed the charge with my credit card, and despite them finding in my favor, Express Scripts is still trying to bill me. Has anyone else had this experience with them? Who do I have to talk to there to actually accomplish them resolving their billing errors? What are my options at this point if filing a complaint with Medicare can't even get them to comply? Help?
