I can't comment on how fruitful complaints to Finnish immigration are. I'm going to guess that would just be a waste of time as well.
The airline
refused to book us on any future flight. We would have gladly taken the flight 2 days out, but that would have meant buying the tickets at full price (they would not even discount it).
