Indigo Airlines — fake recruitment letter

I have recieved a mail from indigo stating that my resume was shortlisted for interview and i have to attend the interview, by paying a refundable amount of 9, 500 rupees as its mandatory. As i have read the mail, and the amount section i donot understand why a candidate should pay a company to get a permit to attend the interview? I don't want others to suffer like this and any company should not ask the candidates for paying to process their resume.
