I had my doctor send a generic prescription for a controlled substance (oxymoron 20 MG er) to express scripts pharmacy because I couldn't afford to pay $95 for the name brand at my local pharmacy. My doctor changed my prescription from a higher dose and ordered generic. I received a bill for $95 from express scripts for the new medication prior to receiving the medication. I called Express Scripts to ask what the bill was for and I was told a prescription for Oxycontin, a controlled substance was in transit. I told the woman I spoke with that I would just refuse the delivery because I hadn't authorized a delivery for this medication and that my doctor ordered a generic. She told me to go ahead and accept the medication and use it and that she would put in for a refund request since I never authorized shipment of the Oxycontin. She told me someone would be in touch regarding my refund. Last week a man called me from Express Scripts and told me that I must return my controlled substance (Oxycontin 20 MG ER) if I wanted to get a refund. I told him it was illegal to return a controlled substance but he insisted I return it. I requested to speak with a supervisor. He told me one would contact me within 24 hours. Today I received a missed call from supervisor Liz. I returned the call but she could not be located. I therefore spoke with Shenekia, Supervisor # P63909 whom confirmed that I must return my controlled substance for a refund. She also informed me that had I refused the shipment, I would not have received a refund and my account would have been sent for review even though I never authorized this shipment of Oxycontin. I also informed Shenekia that not only is it illegal for her to request that I return a controlled substance but Express Scripts policy clearly states online that controlled substances cannot be returned. She continued to tell me to return it if I want a refund. I then requested to speak to her supervisor. She told me one would be in touch but could not give me a timeline.
