scam company changes its name to Ruiwin

I have used Ruiwin as my broker to trade in MT5 from 07 Feb.They urge me to become a VIP with all kinds of bonus. But they don’t tell me the risks. This is, I have to top up to us$200,000 in two weeks. If I can’t then they will frozen my fund and donate to the charities. After I topped up in 25th Feb., they told me that I have to trade at least once before withdrawing. I traded once. Then they told me I have to top up the tax us$22558 for the profit I have made recently. what a scam
