Assuming you gamble on a mid to high-rated gambling website and you won big but they refuse to pay up, what and what are the legal way to make sure that the platform pays up your money?
It happened to many users; the easiest way is to open the ANN of that particular site in this forum and post your complaint.
It is usually observed that site owners followups on such platforms and resolve the complaint. But for the safer side, please don't use the sitwhoseich reviews that aren't good by its existing users.
Most often, reported case are users who have violated the gambling site rule deliberately or unintentionally because I see no reason why you will play on casinos like Duelbit, Roobet, FortuneJack, Rollbit, stake and other reputable gambling websites and wouldnt pay you except when they have technical issues or perhaps have some issues on backend that they are not aware about, such ANN threads are most often than not trolls and cheaters.
If you play and didnt do anything wrong, a casino that has respect itself will pay as long the users is legit, no company want to be sued because they know that you arent just suing them for the amount of money won, you will likely sue them for damages and stress went through.
