I got scammed by Global Prime

Global Prime notified me less than 48 hours before the ASIC Product Intervention Order took effect (which significantly reduced retail traders leverage), resulting in me losing nearly $15,000 in my account. ASIC announced the change 5 months ago. but I was told about it on Thursday afternoon. They said I could either deposit $100,000 to cover the leverage reduction that would take place in the next couple of days, or my account would easily go into margin call and pretty much all my open trades would be closed. And Now I just lost $1,5000.
