Grand Finance Broker Review

I am a victim of Grand Finance . This year, I was pulled into a group by a teacher named Dahai, in which some stock news were given. I am conned to trade SSE and open the account in Grand Finance . I deposited 100 thousand and later added 80 thousand. But I lost 40 thousand or so within one week. I applied for the withdrawal on Monday while Grand Finance postponed it the end of month. I am to call the police.
