I had a similar issue with easyjet
All I was hoping for really (at some point) was an apology. No money back, nothing like that. Just a "sorry for your inconvenience". That would have been enough for me.
What I got was "oh just **** off" from a delightful young lady in an orange easyjet uniform, who "didn't even work for easyjet, so no, didn't care", and a 6 hr delay on a 40 minute flight.
I would like to add that I am very reasonable, polite and softly spoken.
Never used easyjet since. Never will either.
