Flipkart — Refund of debited money

I tried to book a flight from BAGDOGRA (IXB) to DUBAI (DXB) on 13/11/2021, after finishing a booking procedure I paid from Debit card and amount was debited and i got the message "Booking Pending: Your Flight Booking ID: FF[protected] from Baghdogra to Dubai on Nov 30, 2021 for Rs. 20701.0 is pending. The status will be updated in 2 hours. " But after one hour I got this message "Booking Failed: Your Flight Booking from Baghdogra to Dubai on Nov 30, 2021 has not been confirmed. The refund of Rs. 20701.0 will be added to your account" But today on 14/11/2021 i checked my account there haven't credited yet.. Please refund my money as soon as possible because I have to book flight with that money and flight fare is increasing every hour..
