MakeMyTrip India — Undue deduction of claimed refund for flight cancelled by the airlines

Booking ID NN[protected], done on 14th october 2021, return flight ticket of turkish airlines through make my trip,
the airline is ready to give full refund for the cancelled flights, but mmt is refunding jut the base ticket fare which unfare. i tried calling all there helpline nos. but of no use as all are automated response and of no use in this case.
i even tried to book another airline flights but even that option is not available.
in such difficult times how a person fetch so much amount unnecessarily? or they want to punish gullible customers for booking with them?
kindly resolve the same.
