Yes. CX remains one of my favorite carriers, but when they screw up, IME they screw up big (mechanical failure is purely on CX), and they don't own up to it. Write a specific and non emotional letter stating the facts of the flight and that it was unacceptable. They should have made a gesture to pax, which they don't do. I feel sorry for the cabin crew in these cases, as pax turn really really ugly. My 'worst' flight ever was on CX where we were held on the aircraft for 5 hours at HKG of all places. The airlines performance was crap. My partner had a similar experience in paid F. In both cases instead of "customer service" CX stuck their head in the sand.
