I Want My R200 from Yesplay

Am a new customer with them with an account less than a week old .....I made a deposit of 200 with them and opted in on the 100% Bonus Offer...so I started betting everything seemed fine until my bet was canceled and the bonus and winnings were taken without any explanation whatsoever.....now am trying to withdraw my R200 since nothing is said to me but I can't cause the R200 is there but not available for withdrawal....I've been trying to contact them via live chat and email with no success......please Yesplay give me my R200 since you are canceling my bets
