Mango schedules

Flights were booked in the beginning of March scheduled for end of August. Only in the 2nd week of August we were informed that all Mango flights have been rescheduled. This meant that all our plans had to be changed. We would now be stuck at Port Elizabeth airport for over 6 hours. Mango was not prepared to place us on a flight of another airline close to the time of departure. If we were notified shortly after we booked the flights, we would have been able to reschedule on other flights. This is totally unacceptable and I will NEVER book on Mange ever again.
