CVS review: Prescription received

I am soooo angry right now. I just went to CVS because they sent that I had 3 prescriptions ready. I waited in the drive through and was handed out a bag which I thought were the ones I was waiting for. Of course you have to pay before you see what you are getting. Then they handed out the bag it was for a prescription I did not renew or refill as I don't need it anymore. I had 6 cars waiting behind me so I went around and went right back into the store only to be told I can't give it back and the ones I was supposed to get I didn't. So now I am stuck with a medication I don't need. I WANT MY MONEY BACK. Store #3115,
