The service manger does not reply withdrawal request

I met a self-proclaimed chief financial officer of the company on the social networking site. She introduced a service manager to me and took me to operate foreign exchange. When I wanted to withdraw funds, the service manager told me that my account was a risky account and I had to pay a deposit first, so I paid 5730. After that, the chief financial officer told me that I could deposit 3,000 to the be processed first, and I also paid. The service manager and financial officer have not responded since then. I successively deposited about 26000+5730+3000, and lost 34730 in total. Please pay attention.
