Fraud platform. Unable to withdraw Fake website

Three weeks ago, a stranger added me on WeChat, chatted for a while and said that he invests in gold, and told me that he can make stable profits, and double it in a month. He introduced me to the Royal Tungsten platform for trading, and I went to The platform transferred 40,000 US dollars, and it was profitable at first, but after two weeks, the platform began to maintain and could not trade, and then I was about to withdraw funds, but the platform refused to withdraw funds, and told me that my account transaction was abnormal. In the protection mode, I can’t withdraw money, and asked to pay 30% as an asset audit. I transferred another 13,000 US dollars in as required. The customer service said that the audit failed and let me transfer another 30%. I went to their company according to the official website address of Royal Tungsten I wanted to transfer money face-to-face with the customer service, but the address provided by the website was fake, there was no such company at all, and the phone number displayed on Google Maps could not be reached, so I realized that this platform is a black platform. Now the account has 55,000 US dollars, and I cannot withdraw money
