Unable to witdhraw

I’m a Malaysian. I knew a girl from China via Facebook. She added my WeChat and invited me to join a WeChat group. There is a so-called professor who claims he trades very well. Then he induces us to deposit. His partners in the group pretended to be normal investors and said earned a lot. Later, a customer service in 111 was invited in it and asked us to deposit. Someone said they have sent people to see this company to prove it was a reliable company.
I first deposited by a bank of Dama to a company which had no relationship with GUOTAI. I transferred MYB5,000 twice to the company which was designated by the customer service. I lost money because of the so-called professor, president Wu, but he kept asking me to add funds. And I was also dizzy by greed, through the virtual currency, into 3000 + US dollars, spent 15000 Malaysian dollars.
The customer service in the group has been disabled since I want to withdraw, so is the president Wu and the Chinese girl who invited me to join the WeChat group. I asked the customer service in 111, getting the same answer as others, “ The withdrawal will be settled”, “System upgrade”
I will complain about this fraud platform to Bank of China
