Axnfx frauded me for 4800 dollars,

They first called me to start trading with 100 dollars, they make some deals, which no doubt were in negative value, then they told me I can earn more money by investing more. I invested 400 dollars, even those were in negative value, then they asked me they have February offers thier company will give 50 percent bonus, I invested 1500 dollars, they promise me I can withdraw money anytime, they have 7 days return policy, I send them withdrawal request of 1500 dollars, which never happened, and they have given me all wrong deals, and I day I lost all my money, after that also they called me and told me I have to invest more, and they will return my money within 2 weeks, I don’t trust them anymore, now they have stopped calling, and not replying to my messages, anybody can help I have just lost all my savings, to these scammers, I don’t know what to do…
