Take money at their discretion

Playlive casino can cancel or deduct monies on your account at their discretion and as they want. I deposited R300 cash and made R10 000 on their slot games. After trying to withdraw my balance they cancelled they withdrawal and credited my account with R3000. I was told via a message that the the max I could win was (10x) deposit amount. If you deposited R5 000 you qualify fir more tha thec10x deposit. I had also used a bonus voucher - despite turning over the bonus wagering confirmed by their message also stating "10 Jun 23:10 Congratulations, you completed your bonus wagering. R653.70 has been transferred to your wallet. Please note a maximum cap of R1000 is allowed on your next withdrawal". Even this R1 000 that was still on my account dissappeared. I am thus out of pocket of winnings of R8 000 that Playlive just wiped out. I gambled all night long fir nothing. I await their reply to my question as to what would have happened if i won a progressive jackpot with my R300. I have cashed out R18 000 from another online casino with a deposit of R200. I await their excuses
