Money is unable to withdraw

At the beginning, the salesman contacted me by WeChat said that they could help me earn money via some data. At first, I deposited 60,000 yuan, and the technician helped with trading. After I gained profits and wanted to withdraw money, the customer service personnel asked me to pay for 25% of the balance as margin with the excuse of wrong card information. But my money remained inaccessible after payment. They explained that my credit score only reached 80 because of my wrong card information. They asked me to increase the score up to 100 with the price of RMB7,000 per score. I did. The request for withdrawing money was approved but the money would arrive my account unless I transferred 20% of the profits as individual income tax into an appointed account. I didn’t do that. Now, I have no access to the platform. (the salesmen also helped you with a part of payments, but they work with the personnel)
