Unable to withdraw

I withdrew at 21:00 August 2, but did not receive it at 16:00 August 3. I could not contact with the customer service. There were many sellers. But after I transferred my assets to one seller, there was only one seller remained at 23:00 August 2. It increased the withdraw volume more than 8,000, which caused many people failing to meet the withdrawal requirements and unable to withdraw cash. There was no response. They might block us. This fraud platform existed from 2014 and still wasn’t reported.
