Unable to withdraw

The fraudulent trading platform was introduced by Dachang Investment Consultants. When I withdraw money on this trading platform, it is said that I need to pay a 20% deposit when my withdrawal is blocked by the financial management committee. It was originally not covered. Later, their manager MAIL sent an email saying Dachang The advisor Chen Jiaming was willing to negotiate for me to withdraw the money. After Mr. Chen's negotiation, I only paid 400,000 yuan, but I still did not receive the money. Their customer service manager said that I still need to pay a bank deposit of 120,000 yuan before I can release the money. Their customer service manager said that the deposit would be returned three working days after the payment was received. Because they did not release the letter, they asked them to issue a letter of guarantee to me. The money was remitted, but the payment was still not received. No return
