I called Judith C. Hagedorn M.D., M.H.S. for medical treatment. However, I have a reservation for another doctor. So I canceled the doctor's reservation. And I called again to make an appointment with the doctor I wanted. But the receptionist put my phone back on hold. And they don't answer the phone for a long time.
