I hope someone could help me out soon

i have once claimed a NO DEPOSIR $50 chip in this casino. after winning around $1200 it went down to $150 which is the max amount that this chip could win. i tried to withdraw it thru bitcoin wallet so it doesnt get complicated. ive sent my passport and utility bill ahead of time and got verified as far as i know. days passed withdrawal still pending. after almost a week I guess, withdrawal cancelled. 150 becamr $100. according to them $50 chip is deducted as it is not cash able. okay understood. then i wasnt allowed to cash out and was told by support the need to deposit $100 and have to wager the 100$ deposit before I can withdraw finally. what a scam. what a strategy? how can you say a free chip is a no deposit bonus when youre gonna require deposit once won. then the wagering would of course give way to losing both the deposit and the small amount won in the beginning. so who won at the end? lol. i am not recommending this casino. i am so disappointed. very disappointed. so disappointed and dismayed. i hope someone could help me out soon. hopefully.
