Cheating

Can I file a complaint against a girl cheated me? I am a middle class boy joined in a bpo in chennai, there a girl who also took training and working in a bpo get money and cheated me as she can arrange a pg or hostel room in near by. I have to travel every day morning 6 am from the office and I have to cross 70km to reach home. So that I'm not supposed to search rooms in office near by areas. I have only asked to my male friends to get room for me but they are busy in their works, That time she send me a online video as she got room for me and asking 27000 as total (including rent), she also hurried in getting money, I don't have that much amount. Finally she asked to transfer 7000 now and said that she can manage othersum. She got money from me two. Months ago still she asking time to repay. Some times says that if I give a complaint she can manage it with her mom and uncle, as her mom working in government hospital. Whenever I ask for money she simply say I don't have now you have to wait other wise I can manage with my mom and uncle. she also sending me unrelated pics and videos such as her privacy photos. And I have all the proof for her call. Like voice records, and photos. And one more thing I have to mention here, I have her boyfriend number he said that, the girl has cheats so many people and get money after that he said we enjoy with that. As of my knowledge the girl has cheats many peoples in various places. Her boy friend also says that once she comes to his house she took away jewels and money from his home for the value of 1.1/2pown. Now my friend suggest me to give a complaint against her. So please can anyone help me in this?
