No, provider can't take my money. They can only return my bet if the odds were wrong, technical problems or something like this. But the casino decides to pay out winnings or no. My bets were not returned, so duckdice decided to refuse to pay out the winnings.
They... did. They returned your fund that you wagered through duckdice. Your initial deposit were returned to you. All they do was voiding your bets as you previously marked by them [on other casino] as a sport abuser.
I'll ask again as you probably missed it,
what casinos have you been and currently playing so far?
