Cant withdraw and cant reach the people who brought me in on this plateform and they blocked me

I was introduced by a friend Lina. She asked me to depsoit 2000$ and the rest she will do, after the deposit she was forcing me to deposit more as i put all my saving so having nothing i cannot, then they told me that my money will be refunded after 3 month after some days the group manager miss huang jiaqi threatned me to recharge or they will wash my account, as now after three month i tried to reach them and they blocked me they dont reply on email and phone, this broker scammed me
