Sorry I edited my orignial post now let me know if you need more info I don't really have much more though. I never asked to win this damn contest or wanted to win they the ones who gave it to me just such a headache really upset at this casino now days.
I think you should contact their CS to make sure that you won the prize and how to claim it by contacting the event host support, don't hesitate to contact anyone from their team because of course we all can't help you in any case can only direct which is the best, if the site in question is bc. games you need to go to their thread here, hopefully you will get an answer if you post there
https://bitcointalk.org/index.php?topic=5088875.0Make your experience to be more open so that everyone can help you properly also direct you where to complain about your problem, I have seen that the site is bc.games and also see screenshots to make sure that your story in this thread is true not just fabrication which is usually done by other newbies in this forum to seek attention only.
