Make my trip - Makemytrip flight ticket booking Money deducted without confirmation mail or Booking ID

I had booked a ticket from Sydney (Australia) to Melbourne (Australia) for **st June ****. I have not received any ticket confirmation email or message. I chose to make the payment via net banking. Once the payment was done the bank redirected me to MakeMyTrip's website with an error message: "Transaction Failed".

I have checked with my bank and here is the response from them: "As confirmed with merchant, transaction ******** has been successful and settled from our end on ** June ****. For more details kindly contact your merchant."

There is no refund from Makemytrip. I have tried reaching Makemytrip on multiple numbers provided on the internet, none of them worked.
