I have been swindled

Chen Jiaxin, a girl I met on the Internet, induced me to invest in foreign exchange, saying that her uncle had insider info to invest in. Every time I entered the market, I made a profit. Small withdrawals went smoothly in one day. When I wanted to withdraw 5,000 US dollars, The customer service said that the system has detected illegal transactions and that reverse engineering is illegal. How would I know what reverse engineering is, it is the quotation given by the girl. The customer service also asked me to deposit 5000 as the authentication fee before I could use the account normally. Otherwise, I would freeze my account after 3 days. The traps of fraud were layered by layers. I called the police but the police said that the chance of getting the money back was very small. I would like to inform you that if you don’t understand, don’t try it. It hurts. I don’t know if it’s this person. This is all my information. I hope everyone will open your eyes. Scams are endless. There are hundreds of ways to deceive you. They may meet every day to discuss how to squeeze out your money. Really It's hard to guard against. I'm not familiar with it, don't meet, don't take risks without detailed information.
