Money was withdrawn two months ago but has not yet arrived

In June this year, I deposited 4,000 US dollars in XCOQ and the trading account 630240. I lost a great deal and less than a thousand dollars left. In October, the platform announced to withdraw from the Chinese market, and asked the investor to close orders out and withdraw money. But my balance has been deducted while I have not received the money until now. The customer service personnel said the money would arrive at most on December 15th, and the mail also showed the same date. But the money has not been received, and they don’t reply my email in recent days. They customer service personnel make no answer. Is it ready to run. I have lost so much, and they still do not allow me to withdraw the rest small money
