my docter called in a prescription for acid reflux at the giant eagle pharmacy, i went through the drive through i was asked my name and birthdate, paid and was handed a paperbag stapled with what i thought was my medicine. since i was having heartburn i drove away from the window...less than 100 feet and open the bag to take the medication. i realized they had given me the wrong medicine and immediately went back through the drive through to make them aware of the problem. they immediately ask me my name again and got the correct medicine but told me they couldn't take the wrong one back or give me my money since i drove from the window without checking . there is nothing on my receipt that stated that i have to keep the wrong medicine medicine because i drove away. some one tell me what to do.
