Seller lied and sold me broken nonfunctional phone.

I wanted to buy a second hand windows phone and found a good deal on quickr.com . she posted that phone is as new as brand new without any scratch. data cable, invoice and charger was available. she posted that phone has minor defects but it will not affect the PERFORMANCE and look of the device.after several attempts of bargaining that seller who is a girl agreed to sell me her Nokia lumia 1520 at the price of 6200. doorstep delivery was not provided by the quikr. so we agreed to met outside the dwarka sector 10 metro station, gate no. 2. i told her that at least charge the phone 50 % so that i could check it thoroughly but when we met battery was critically low and shutdown after clicking a photo..i asked her about the bill but she replied that it was an gift but she said that it was bought in 2016..since the screen was scratch less and everything looked fine, i gave her the money and came back home..when i started charging the phone i found that it was not charging..later i found that its both charging port and the charger that she gave me are not working properly.micro sd card tray was missing that she hide it from me. that phone had major hardware and software issues like after charging it several hour phone was charged only 13%.. sometimes it shows 50 , sometimes it showed 30%..i called her and she said that use some other charger or powerbank. i tried that to but nothing happens .. later that night touch screen stopped responding and now i cannot even start the phone. it is completely dead. i called her and requested her to please take your phone back..and return back my money..you lied to me and intentionally did not charged her phone so that i could not see the other defects..she cuts my phone..after that i called her several times and even now i am calling her but she is just not receiving it. i called her from different number but she is just not receiving any unknown number. i am feeling something is wrong here. Sir i am a very poor and honest boy..i have never been any situation like this when especially it involves a girl.i mailed it to quikr but they just ignored my complaint against that girl..i do not know what to do..does that come under any forgery law ..she mislead and hide important details and robbed me..please sir tell me what are my legal options now. i do not know where she lives and work.. except screenshots of her ad , her name ,phone number her photo and information about her ad id and our chat details, i do not have anything else..will police help me if i go to karol bagh police station..since she is a girl and it seems that she belongs to some rich elite famliy i fear that police will not help me.please tell me what to do next. wht are my legal options to get my money back..thanks
