I suffered losses after making money hardly (I have called the police and hope to catch the gangster)

Because I can't work during the internship recently. The internship salary was only 3000, which was far from enough to live. I went to find an online job and met the following girl. Originally, I applied for a praise of 20 yuan. Later, she told me that there was no shortage and asked me to turn into a trader. Later, she said she could teach me by hand and cheated me into deposit for various reasons. In this way, I paid the money foolishly and lost all of it. I hope the platform and the police can help me recover it. Thank you.
