Walgreens review: prescription filled for a drug I am allergic to & refused to take back & refund $50

My Doctor called in prescription ear drops. My husband picked it up for me and when he brought it home I noticed it is related to a drug I am allergic to. Next day after calling my doctors office to let them know they prescribed a drug I am allergic to, they called in a new prescription. I went to pick up the new prescription & requested a refund for the drops. The drops are in a sealed box with a sealed bottle inside. I did not open or disturb the seals in anyway. They refused to take it back. The pharmacist said they would have to throw it away & would not return my $50.00. This is not the 1st time this has happened with this exact same drug. The 1st time it happened, I noticed it right after I got home from the pharmacy and went right back & was given a refund. Shame on my doctor for prescribing me a drug related to something I am allergic to, but I have my allergies all listed with Walgreen's & I count on them to be my 2nd check to protect me for taking a drub that could kill me.
