OTM Trade refused my request for withdrawal. I was scammed of 170 thousand RMB.

I traded normally and then applied for the withdrawal. The platform gave no access to my withdrawal with excuse of wrong bank card, asking me to pay 10% of the fund to modify the wrong information. Then it asked for another 60 thousand RMB since my credit score has decreased due to the wrong information. I needed to raise 20 score, with 3000 RMB per score. After that, I was still asked to pay 100 thousand RMB for withdrawal. Otherwise, high rollover would generate and all fund would be froze. But my card could receive out-boundary remittance after verification. Thus, I was scammed by the platform. Meanwhile, the platform hasn’t registered company in China.
