Infosys BPO — Money given not returned

Address:

Residential road, Bangalore

I had been called for a interview by Infosys BPO located in residential road Bangalore .
I attended the interview and got selected, I also submitted the required details . They asked me to pay a sum of 1700/- which was refundable, I even paid the money .
Later after months also I didn't receive any calls regarding my job .
I patiently waited then I went directly to the office, they asked me to again pay 2000/- for training which was for a month so I again paid . The training happened just for a day which happened online .After that no call nothing I'm calling them everyday, I haven't got my money back also . I sincerly hope I get my money back.
I'm still a student and this first interview and the whole story makes me lose hope
