My suggestion is to keep calling, whenever someone said they would investigate and get back to me they never actually call back so give it an hour then call again, ask them to contact the partner airline too and request the booking be reinstated if they haven’t tried that alreadyJust had the South African call centre cancel my business classic reward to. Had a sector by another carrier reschedule which would have mean we missed our flight from HK back to Sydney (the rescheduled flight landed after the connection would have already left). Called to ask them to reschedule the connecting flight which was done, but they cancelled the sector with the other airline. Spent 8 hours so far and they are doing an investigating. Fiji is blaming the South African call centre but no one can fix this!
They are doing an investigation now but I'm not confident I'll hear anything back... Any suggestions on who else to contact?
Hope it gets sorted for you
