Malaysia Airlines review by Paul

I booked a business class flight from Perth to Guanzhou leaving 1st July 2023 Booking ref 6FMVNV Malasia airlines then cancelled the return flight. Their suggested alternatives did not suit me so I phoned theiir Sydney office who told me I must cancel via website and that there would be no cancellation charge. I cancelled via their website and was charged $500 cancellation fee. I wrote to them and their response was curt, and basically told me I cancelled the incorrect way. Tough luck. I'm now hesitant to use them again as even though I'm a business class customer, I get treated as a number, not a person.
