Jet Airways — I'm complaining about fake recruitment

I received a call from HR department of jet airways and they told me to send my documents to their mail after that they told me to pay Rs.2000 for the first round which is online aptitude test and they said If i didn't get selected it will be refunded.I paid Rs.2000.But the link which they sent for aptitude test was not unique for me. After that they called me and said to pay Rs.7000 for the second round. In HR department Rajesh said if I canceled it without paying Rs.7000 they will blacklist my profile. So, this was the problem I'm facing.
