With the platform’s teacher, I have been cooperating, but my messages have not been replied to, which seems to be suspected fraud. They even maliciously attributed the losses to my account. When my account balance was at most just over USD 10,000, somehow the total loss reached more than USD 20,000 at the same time. After the account went negative, it was still able to incur an additional loss of more than USD 10,000. I request a refund of my principal of USD 10,000.
