Unable to withdraw

my money is stuck from last 8 month. 2800$. unable to withdraw my money. I paid tax and everything. I put all my money with this platform but no return. on behalf of withdrawing they asked me to pay tax. I paid 566$ tax also. I need my money. I have all proofs. I deposit for earning but they ate my money. they say I trade many time in a single day. so your account is Freez. this is no sense of trading platform. after sometime they change my account from Titan to yun shang hui Xin limited. they change everything. they ate my money. help me to withdraw please
This one is last transfer as 566$ they asked me for tax to withdraw my amount, and I deposit. After they say you traded many times in a single day , your account has problem. So deposit more 500$ for inspection. But I refused to deposit more and they say we will not withdraw without deposit. After some time they say we will give you withdraw after sometime , but now they prohibit my account
