Tricked to participate in the activity, the account is frozen after the activity and cannot be withdrawn

I met a friend on the WHATS APP earlier, and soon after he said he would take me to do MT5 foreign exchange transactions, and use the SHENGHUI foreign exchange platform for transactions. You can actually deposit and withdraw money at the beginning. Later, my friend told me to join him in an event that required an investment of $200,000, so I used my own savings and borrowed a little to put it into the account. When the activity was completed, I wanted to withdraw the money, but the customer service said, "Your account has been transferred multiple times to multiple accounts. The platform risk control system will automatically review your account for suspected money laundering, and the system will freeze your account for risk control. You need to Submit your front and back ID cards and your recent running water to the customer service for verification." So I handed in all the documents. A day later, their customer service informed me that I would have to pay a deposit of 300,000 before unfreezing the account to withdraw funds. I felt cheated. Even this friend felt like they were cheating on me together. They kept asking me to deposit money into the account, and also helped me to transfer the credit card money into the account. I think that even if I pay, I will not withdraw the money, and it will take ten days, otherwise the account will be permanently frozen or three times the deposit will be paid. I just want to get my account back over $200,000 now. Hope you can help me with that. The whole matter happened within this month.
