Arrived at check-in early, informed that the flight was overbooked and was offered an alternative flight and for my troubles offered a free flight, as compensation.
Decided to take this offer, then at the end of check-in, was informed that there was room for me and so had to take the flight. If I did not, then would have to pay extra for another flight. I felt used and cheated.
On informing the team at the desk, they would not recognise that they had done anything wrong, after complaining when I returned to UK, received the same company line, policy.
Has anyone else suffered the same? Is there some body that one can complain to? I really do feel very annoyed the way I was treated....
