Safair Refund request - Exceptionally poor service

I had to make a business trip to JHB from Port Elizabeth. Checked in to departure area through security. Departure/flight information screen showed Safair flight to have been delayed "indefinitely". Went to Safair kiosk outside security area and was told that the flight had technical problems and had not even left JHB yet. Had to book a flight on another airline at 4xtimes the normal price. Was assured by Safair personnel that I would be refunded. NEVER happened, one month later after numerous email requests and telephone calls was informed via email that the flight was only delayed for 3 hrs and 50 minutes. Cut off time for a refund is 4 hours. Not once did the Supervisor even bother to get back to me. Exceptionally poor service. Used to enjoy flying Safair -- Never again!!!
