I booked a two way flight from Brisbane to Cairo with Booking Ref VZ6NXW. I rescheduled my flight back to Brisbane on 30 July 18 to fly on 12Sep18 with Qantas flight Centre at Cairo. On my flight day to Brisbane I was told that my flight was cancelled. I contacted Qantas flight Centre at Cairo as well as the flight agency in Brisbane and couldn't get solutions. Finally I was forced to buy a new ticket and came back.
