Induce and cheat me to participate in the activity to embezzle my account funds

I found out that RUI WIN CAPITAL was a regulated investment company platform at first, so I opened an account with it without worry. And I was able to withdraw successfully after the initial gold spot trading operation, but then I was induced by the customer service and the introducer to participate in reserving the 500,000 margin replenishment activity of the company. After the confirmation of participation, the customer service informed me of the detailed activity rules on LINE: Once I have participated, it cannot be cancelled or changed! And if the deposit cannot be completed within the specified period, the client will be regarded as a dishonest user, the account will be automatically frozen, and it is claimed that the account funds will be donated to the International Red Cross. I haven’t received an official email to confirm all of this. I didn't realize it was a fraud at first, and my introducer, Chen Wei, was confirmed by the platform's customer service to be qualified as a guarantor for my participation in the activity, and he also promised to assist me in completing the deposit. So I was assured that after participating in the activity, I deposited more than 70,000 US dollars of funds gradually. When the deadline was approaching, I found that the guarantor could not help me complete the activity as he promised, and the original official website of the platform was also unable to log in on January 21, 2022 suddenly, and then I realized that I had fallen into a trap. I checked the relevant warnings of the Australian Cyber Police and found that this was a typical fraud behavior. Through talking with the guarantor Chen Wei on LINE, I learned that his account can be preserved, but my account cannot be withdrawn. I infer that they may be a group at all, so I expose and report them here, hoping you to intervene and help me get my money back.
