Trading platform, unable to withdraw funds

I met a Singaporean man on a dating app and asked to add Line to chat.
During the chat, the conversation became more and more joyful. After gaining trust, we talked about work. He said that he was doing IT-related work and asked to invest Usdt to help make himself more relaxed and not to work hard. At first, he did not want to involve money with each other, but he was told no. Trust and hard words asked for investment efforts, hoping that it would be easier in the future, so I invested one after another. The first and second time I invested a small amount, so I was able to withdraw money smoothly. After that, the amount increased to more than 60,000. That is, it is impossible to withdraw money. I was asked to pay tax, and some asked about the tax deduction directly, but the customer service said no, and netizens who asked about it also said they had to pay it back and asked whether they should handle it (because netizens also invested half of the money). I borrowed money to pay the tax under semi-pressure, but the customer service refused to withdraw the coins. It is required to pay a security verification fee, and there are more... I asked netizens and said that it is necessary to pay, and said that the regulations are different in each place, and that it must be paid from one's own account, and is not allowed to be paid on behalf of others. I am being oppressed to borrow more to pay the verification fee. , I wanted to withdraw the coins after paying, but the customer service again refused to withdraw the coins (withdraw money). They said that the account was at risk of being stolen and that account security verification must be installed for security verification. The risk amount was more, and I couldn’t get the money to pay around 100,000. Usdt, netizens also said that they could not get it, and they asked me to show my attitude towards handling it. After that, there was no contact. I... was defrauded and reported to the police. I hope someone can help me. Thank you.
I hope it will be exposed so that no one will be deceived again.
