Cleartrip — did not receive an email about flight confirmation

I have booked a round trip from bangalore to mumbai from 2/3/2019 - 5/2/2015 on 15th feb through cleartrip app.

I have completed the transaction and the amount of ₹7118 is deducted from my account that i paid via paytm.

I have received an e-mail from indigo about my return flight details but nothing about by departing flight.

I would like a full refund if my flight is not booked.
