You must write complain to GM
Airport staff, they were cheated with you
Actually, there are no D-fare on domestic flight
Business class fare of VNA domestic flight is always C, for international flight are D or J
Even Y fare permitted to change flight free of charge, not talking about C class
You can fill the complain in flight, just ask flight attendant to bring the form.
