Quicker Job — Fake job opportunity and not refunding money

I applied for a job opportunity on quicker job and my profile was accepted by apollo hospital (As per the mail) as a general physician. Later they asked for submission of amount of rs 2500. After submission they notified that you are not selected and your money will be refunded after you pay rs 450.
What is this? They didn't informed this earlier and now the person named sandeep rana from gurgaon, haryana is asking for gst of amount of rs. 450 for refunding. I did not find any such refundable policy on site. Kindly see to it.
