on 8/6/17 i was at oxford casino and was playing a game of black jack with 3 match bonus. 9 to 1 for any player whom two up cards matches dealer one up card ( either 3 of a kind ,straight or plush ) I was at the first black jack table that faced the entrance door At around 2 or 3 AM a man put 50 dollars on the bonus and i put some money in my spot. After the dealer deal the the first round of up cards to the players then takes a up card for herself she then deal the second up card to all the plays she then take a the last card for herself ( this last card that she took for herself she must keep it down ). after the second card deal we will now can see that if the player cards matches with the dealer up card .if it's a match then the dealer have to pay the player 9 to 1. The man with 50 dollars on the bonus spot got a straight and I got a black jack, but when the dealer take a last card and keep it down insteal she turns it up and just because of that she call her boss over and she decited that a misdeal and refused to pay the man with a straight ( 450 dollars) and me my black jack It's a shame for Oxford Casino to cheat on people this way . I for one lost thounds of dollars in this casino will never coming back to this casino ever again .at the end the casino will lose thounds time more 450 dollars
