Career Builder — fake call

I recd phone from a lady...she presumed to be a recruiter from career builder...she asked to pay rs. 2500 stating to be her recruitment fees and asked me to submit my documents (Pan card, Aadhar card, marksheets). Next day, she called me stating that my documents have been verified by bank and interview will be scheduled next day for which I have to pay Rs. 7500. She told me thats refundable.Next day, some lady pretending to be from HDFC bank took my interview asking just some basic questions and said that I have been selected...she was not even able to speak English. Nextday, I got a call letter from HDFC bank in which there are many spelling mistakes...even the address mentioned is not correct. They demanded Rs. 20500 as company training charges...I paid the amount thinking that this is a golden opportunity which was my biggest mistake.

Kindly guide me as to how do I recover the amount from that lady.
