Shocking service from Fly SAfair this morning at OR Tambo!!

Mine and my partners flights were booked to East London on 9 January to depart in the evening on 19 July 2018. In May we were notified that the airline was changing its flight schedule and our flight no longer existed. SAfair changed our flight without our confirmation to the morning of 19 July 2018, which we were not able to make. My partner then called SAfair to let them know and re booked for a flight that we were able to take on the morning of 20 July 2018, this morning. The change of flight was confirmed by the call centre agent. When we arrived to check in this morning we were told that we were not on the flight and had to go to ticket sales to ask what the problem was. Bearing in mind that this 07:10 flight was the only flight that SAfair had for today to East London. The attendant said we should re-book and pay again and that was our only option because the flight on her schedule was for 19 July which was yesterday and we had missed it. When we requested a supervisor we were told that she was at the gate and they could not call her. The attendant could also only call the call centre to confirm what had happened at 07:00 when it opened. By this stage we had missed our planned flight. After reaching the call centre it was found that the call was recorded and the call centre agent had confirmed our change of flight for 20 July today, however had not changed it on the system. After finding out it was SAfairs fault the attendant asked us when we would like to re book the flights for. These were rebooked for 2019. We have had to both take off work today as well as get taxi services to bring us to the airport and to take us home again, canceled meetings in East London. This is unacceptable, what is our compensation for this terrible call centre service, our leave from work, time and money wasted!!?
