Deposit 15,000USD, the unscrupulous platform swallows the principal

The unscrupulous platform swallowed up 5,000 USD of my principal and claimed that it was the bank's fee for checking my order, which was offset by my balance. The principal of another friend of mine's account of US$10,000 was also swallowed up, and he did not receive any email explanation. Total principal of $15,000. It is purely a scam platform. The customer service in Malaysia also blocked my WeChat account. He also changed his WeChat ID and now I can’t search for him. The IP has also been blocked, and there is no customer service online on the official website. No reply to email.
