Sorry to read about that but Curacao are really just a tin-pot useless organisation that give a fake cover to anybody applying for a licence when the websites they cover could just as easily operate without it. It was still a good idea to contact them first just in case they arbitrated and helped out but sadly they proved to be as useless as their licence and badge being displayed on several gaming websites.

I suppose that leaves only the legal route, is that what you will do next? I would hate to be in your position losing out on 19 BTC because of a trash scam website that selectively scams winners. If they get away with this will keep going trying to scam others too and the problem is compounded by spending more money on legal fees considering you are already 19 BTC down.
