[Resolved]  Indigo Airlines — fake job offer

Dear airline team,
Recently i have received a mail regarding an interview at indigo airlines office at hydeabad. I have paid ₹9600 as security amount as it is said it will be refunded at the date of interview. The bank slip and documents where sent to the mail id "[protected]@goindigohrd.co.in".

Later i received another mail to pay ₹11328 inclusive of gst. As per the conversation with one of the hr team member mr. Sumit rana i cancelled my appointment and he said he will refund the amount. Later he is talking rudely and threatning.
Please confirm whether it is a fake call or not. And do necessary action for the same. I'am also attaching the mail i received.
