MakeMyTrip India — Transaction Failed but amount debited

We tried booking a hotel through MakeMyTrip. I did not log into MakeMyTrip while doing the transaction. My amount of Rs.89918 has been debited but the booking has failed. I used HDFC netbanking.
When can I get back my refund?

Please confirm if I need to take this legally?
