I fell into a trap

3 years ago I went to the cinema, and this film had a prize draw. I wrote my name in the ticket and I participated in a draw.
4 weeks later I received a phone call! I was the winner!
A person said to me what I won a travel to the Alpes and for free!
I prepared my kit very happy but...
2 days before the travel I received a phone call again. This person wasn´t the previous one, he was the boss, and this man said that the travel wasn´t free! The travel costed 3.000$!
And in the end I didn`t go to the Alpes. This draw was a trap!!! I got very angry!!!
