Cosmo Group — Taken amount of Rs.6000/- but now not responding since one month

In August 2016 I paid an amount of Rs. 6000/- for a job at Hyderabad but till today there is no response from them.
Till I deposited amount I got continuous calls from them but after I Paid the amount they are not responding my calls atleast.
In between I only tried to call them and whenever I called only this Ankit used to respond. and all the time he gave only one answers that now there are no openings and he vll let me know if any.
And this payment validity is for only one year and in August 2017 my it vll expire. I'm not understanding what to do now.
The Person who taken amount from me is Mr. Ankit.
