So what exactly is your complaint about? Not getting paid or just about withdrawal limits for their bonuses.
If its the 2nd then Im afraid you got no case, as pretty much every casino
out there has max cash out rules on a bonus.
On top of this if you don't like such terms, then why play with bonuses? You can always decide not to take the bonus, hence you won't be limited when it comes to withdrawing your winnings.
And lastly, please refrain yourself from attacking LCB
