[Resolved]  Indigo Airlines — interview call

Hi I am Asath, on 16th August 2019 i received a mail with a call letter from indigo regarding the interview process to be held in 24th August at Bangalore. They asked to pay an amount of Rs. 8900 plus GST as a security deposit. This was for air tickets, pickup, drop etc. I first made a payment of Rs.8900/- and later on they informed me that I should make the make payment including taxes Rs.10, 502/- and they will refund the Rs.8900/-
After payment, they sent an application form with few details.On that same day i got a call like there is an opportunity of direct joining without interview and i am one among them. Rs. 40, 000 has be paid as a bond which will be refunded after 18 months. I didnt gone for that offer, so they said they will refund Rs.8900/-.
But they haven't made the refund yet. Please help me how can I recover my money back?
