Black platform blocked the withdrawal apply and its account manager did not explain the reason

After making a few USD/JPY transactions, the client found the spread was extremely large. And the rebates were rare. So he planned to withdraw all the funds. The customer service of the platform replied that the account was abnormal. That's all we got about this thing. No respond from the company. All transaction records of mt4 were deleted. Withdrawal was always in processing status. This is purely a black platform with poor service attitude and does not allow investors to withdraw funds.
