Dr. Mast explained my situation so I understood. Very satisfied. Dr.Mast worked me in for a scheduled appointment that scheduling had changed my time without telling me. They said, they called me and left a voicemail which I saved and they "did not" say anything about changing my appointment time and the call lasted 8 minutes. I did show the doctor on my iPhone and the receptionist who was extremely nice. Anyway it all worked out ok.
