Substandard customer service rendered in many corporate institutions can improve if staff who violate customer service protocols are sanctioned.The observation was made by a Lecturer at the University of Ghana Business School, Bob Hinson on the Super Morning Show.The discussion on the subject of poor customer service was triggered by a survey conducted by Joy Fm.The survey sought to ascertain the phone etiquette exhibited by client-service staff of a number of institutions including the ECG, Korlebu Teaching Hospital, and Databank among others.Professor Bob Hinson says corporate bodies can no longer make excuses when staffs are uncouth towards customers.
