The customer service didn't reply, didn't answer the phone, and asked me to put in another 450,000.

I joined a group on Facebook. It looked quite formal at first, just ordinary messages about what products I liked. Later, a "lecturer" came to lead us to follow orders, but I hadn't followed it yet. Not long after, the club had an event to participate in. I watched for a long time and found that many people went to participate and did receive money, so I followed them. I went to private chat with the "lecturer" and said that I also wanted to participate. I deposited 120,000 yuan. The event said that there was no need to remit the money first. The lecturer would advance the payment, and we would return the principal when there was profit. You can choose to remit or return offline. I chose offline because I thought it was safer. These are all my ideas. Finally, I deposited 120,000 yuan into the virtual currency wallet, and the "lecturer" sent me his wallet address, and I transferred the money to him. After he received the money, he took me to withdraw the money. He said that he had to privately message the platform customer service to confirm my money, and then the customer service kept delaying. They said they needed to confirm whether there was enough USDT, asked me to provide a video to prevent money laundering, and the Financial Supervisory Commission required them to strengthen auditing and supervision. I didn’t know that the lecturer had used illegal methods to make us profit. The platform said that I had to deposit 450,000 before I could withdraw. Only then did I suddenly realize that I was scammed. Until now, the "lecturer" has not replied to my messages. I called him frantically, but he didn't answer. After that, the lecturer created another group with a total of 11 people. He said that he was discussing solutions with other lawyers and professionals to solve these problems. But there was no news for a long time. I went to Google to check this platform and found that it was a scam.
