Shoppers Drug Mart complaint: UNFAIR DECISION NOT TO TAKE BACK MEDICATION

I’m diabetic and I refill all my medications at Shoppers Drug Mart at York University. On or about September 8th, my doctor added Forxiga to my medications. After taking it for about ten days, I was uncomfortable with the side effects. I had a virtual consultations with my doctor on September 21 and 28. During the call on September 28, my doctor advised me to stop taking the Forxiga. Meanwhile, Shoppers Drug Mart had delivered 3 months of Forxiga to my house for which I paid a little over $300. I had used it for less than two weeks before my doctor told me to stop. I called Shoppers Drug Mart Pharmacy on September and explained to them that my doctor had advised me to stop taking Forxiga. The medication was packed in 3 boxes and each box is for one month. I had opened only one box while the remaining two boxes were exactly the way it was delivered to my house. I pleaded with the guy on the phone that I wanted to return the unopened two boxes so that they would refund me the $200. He told me he would talk to his superior and get back to me the following day (September 29). He called me on the 29th in the late afternoon and told me that his superior had advised that they won’t take back the unopened two boxes. I pleaded with him that it would be unfair for me to lose $200 and that I pay for my medications since I don’t have any prescription coverage but he said it wasn’t his decision. I’m filing this complaint because this is an extremely unfair and unjust decision. I buy all my prescriptions at that pharmacy. More often than not, I refill for three months at a time because I don’t want to be going there every month. All of them at that pharmacy know me very well, yet that counted for nothing. I can’t just lose $200 in such unjust and unfair manner
