On March 11st,I opened an account and began to trade next day.On the other day,I applied for the withdrawal of $300.the platform sealed my account,allowing me to look.I argued with the customer service,why you ban my account?What’s the reason for declining my request?They just explained that it was in audit and their email sent on 20th couldn’t account for anything.On 26th,they sent me the email again,saying that I was straddling,and I must sign a document,which only give back the fund.I responded,asking for evidence.Nobody has replied to me till now! What platform it is?
