During the runup to the Champion's League final I entered a competition run by an American organization called Omaze. They are apparently a charity organization, which makes its money by running competitions and taking a cut.
One such prize was tickets to the UEFA Champion's League final. I spent some money, but now suspect the competition to have been fraudulent ie, no prize. They refuse to supply any evidence that this prize was indeed won by anyone.
Further investigation is ongoing
The only evidence I have seen so far is a poorly art directed email with someones face, some fake confetti and the word "winner". The winner looks remarkably like one of their employees.
