Unfair practice and fraud !

Audiolens hosted a giveaway to win a nikon bundle the start of september . I entered the competition because this would be a huge benefit to me as i just started a makeup account and this camera would of been amazing for tutorials and pictures . This camera would of actually go to use . audiolens stated that the most liked post would win . At the end of the competition i managed to get 1.3K likes with the help of my family and friends . I noticed some people buying their likes (not mentioning names) , i then told audiolens about this and they then said they would all be disqualified . Anyways the day came and the winner was announced , and somebody won that only got 100+ likes HOW ? Besides the fact that i got 1.3K likes , there were people that even got more likes then the person that won ! Thats unfair towards everyone that entered and its fraud ! they then said the winner was supposed to reside in western cape , which i do . apparently "facebook" chose a winner ? Thats Totally unfair , which means i worked hard for nothing ? I was initially going to leave it , because im physically and emotionally drained from this competition . But then i Decided to take action because they played unfairly . I hope justice will be served ! They just lost so many Potential customers .
