Sony — Harrasment and Cheating

Sony India held a contest at Facebook in which we had to get maximum likes to win a contest. I managed to get the maximum likes after working hard day and night and in the end sony people gave prize to someone who was not even in the top page of votes. THEY GAVE PRIZE TO THEIR OWN PERSON! THIS IS VERY UNFAIR! I NEED A REASON FOR ME NOT GETTING SELECTED BECAUSE I HAD THE MAXIMUM VOTES AND ALL MY VOTES WERE GENUINE. IF THEY WERE FAKE, I WANT A PROOF! THIS IS VERY VERY UNFAIR AND BAD!
I have attached an image showing that I had maximum votes @ 12 PM ( The time when the contest ended).
