Unable to withdraw

Meet a netizen at IG at the end of March!! Afterward, he continued to ask me to invest in gold. At first, he invested 10000 yuan, and then he invested 30000 yuan. Soon after, he said the market was good and asked me to borrow 200000 yuan Okay, I borrowed it and only invested 150000 Afterwards, he said that the market was good and he wanted to help me deposit 10000 US dollars. After he helped me deposit, he also said that there was an activity and asked me to ask customer service. The customer service said there was an interesting activity, but I felt suspicious and insisted on not participating. He raised the deposit, but the customer service said that there was a third-party intervention in the funds, so he had to pay a 20% tax. The amount is 3560USTD, and currently, he cannot withdraw the deposit
