Since OP is satisfied with the outcome, I can't support the flag anymore and will therefore delete my support for it. The negative feedback for the casino will remain until the backlog of unresolved accusations has been resolved.
I had trouble withdrawing money from other casino and I ended up losing the amount I wanted to withdraw. They gave me at least compensation to make up for it.
It's a matter of their goodwill to do that. They are certainly not required to give back the money you gambled away. I would say you were lucky to get something back that you originally didn't have. No idea what caused the delay with withdrawals in the first place, though.
Didn't you know that placing bets on the same game and in the same market is not allowed?
Placing bets on any market that is open and available is allowed regardless of what the bookies try to tell you. If you don't want bets to be placed on a selection, close the market and don't open it again. If you don't want a player to play on your webste, limit him or ban him after paying out the money they are owed.
Usually the user would get limited before they've placed a bet, but in this case, the bet was voided 5 days after the bet was settled.
And if that limit happened before, it would be ok. But since both the casino and betting provider accepted the bet, it should be honored. You did the right thing in the end.
