Account closed, winnings and deposit confiscated, no reason provided

28.10.2016 I opened account at winnerclub.com and get free bonus. I won 200 usd and wanted to make withdraw but I cant I asked what must I do and support agent said that I must send documents and make deposit of 50 usd. I did all they ask and after 5 days I was able to withdraw I made withdraw request of deposit 51 usd and winnings 200 usd. My account was verified! Today I tried to login and see that my account is blocked. I did not use vpn or other soft and sent them all documents. I did not brake any rule! Help me please! I think they want to steal my deposit of 50 usd,
