MakeMyTrip India — Flight ticket booking by Mohan Samuel

I yesterday booked a flight ticket from Raipur to Kochi, Kerala, India using Make my trip site . In the site they had not displayed a direct flight available from Raipur to Kochi and so I booked another convenient flight but later in Indigo site I saw a direct flight. This is cheating by them and harassment to a senior citizen.
I need this to be changed without charges to be changed to direct flight.
Details of Booking-
PNR -LTKW2A
Date of Journey[protected], From RPR TO BOM, BY 6E5032.

When direct flight was available from Raipur your SITE deliberately has not shown that flight
