I was scammed and lost my money

FX Broadnet took all my money!

I have opened an account 3 months ago but changed my mind
due to their banking practices.I was told to trasfer to agent Arina 450
USD. They refuse until today to refund
the amount I have placed with the account. The agent "Arina" is
claiming I have to trade first. But I lost any trust. Also because not any of
my e-mails requesting clarification has been answered. If anyone has experience
how to push them to pay my money back would appreciate your comment.
