Rusdav offers no access to withdrawing money

In the morning of May 1, Ruida’ MT4 suddenly couldn't be use via mobile phone. It is said that the platform had been reported, and the police had filed a case.
On May 2, I received an mail, saying that the server would be shut down, which causing orders to be closed out forcibly. Most of orders should have been closed out, but now I lost about 500,000 yuan. I withdrew the rest. Now the platform delay the money withdrawn with the excuse of the new regulations of the Australian Regulatory Commission. Money being withdrawn used to arrive after one business day.
(Now it has been 10 days since I withdrew the money) This platform does not even have a company phone call, and I can not contact with the customer service personnel on the website. I have sent mails but got no reply. I doubt that the platform is in trouble. The garbage platform!
