MakeMyTrip India — Deduction of convenience fee in flight cancelled by Airline

This has reference to my booking ID NF2VVTBN6DJOF1UA5991 for Ranchi-Delhi Go first flight scheduled for 7-2-22
The flight was cancelled by airline and full refund was given, but Make My Trip has deducted a convenience fee of Rs580/-, which is unethical as booking was not cancelled by me.
I would request MMT to refund the amount at the earliest.
