Very very rude receptionist

Dr J van den Berg in cullinan, the doctor is fantastic, friendly and gives very good medical care. His receptionist on the other hand is extremely rude, hangs up on patients over the phone THREE TIMES, we called again and she just picks up the phone and hangs up again, it's not acceptable for a person who clearly doesn't want to work with people to work with patients who needs advice of letters from the doctor.
