    Dr. Buster was, as always, very helpful and listened to what I had to say. He instructed the scribe to send two prescriptions to my pharmacy. When I went to pick them up, there was only one. I called the office and found out that for some reason, she had sent them to two different pharmacies. They were then supposedly electronically sent again to the pharmacy I was at, but she faxed the one I was missing and electronically resent the one they already had. The woman I spoke with at St. Joseph Heritage, was extremely helpful and very upset about the error. She ensured me she would take the error up with the scribe.
