The broker asked me to offer deposit history in case of money laundering. But they said the histori mismatched after I offered the deposit history without a resolution. Now the customer service doesn't apply to me.

ETF 3 times contract, the platform increased the price by 600%, while my assets did not increase, after the increase of 600%, I began losing money, the increase of 600% increased the rate of liquidation, and the platform deleted all my transaction records after complaining to the customer service.
