I knew a person whom said that forex trading could be profitable through WeChat. I took a chance and deposited 120 thousand yuan. When I applied for the withdrawal, he still asked me to add fund. Without doubt, I borrowed some money from relatives and loans, totaling 700 thousand yuan. At that time, I was aware of the scam, but they kept inveigling me to add fund. I keep all the chatting and remittance record. What should I do?
