MakeMyTrip India — Wrong Cancellation fees charged

Hi, As per Air India airline the cancellation fees is Rs 3500 + GST whereas Makemytrip charged us 7600 + GST for the cancellation which is not the appropriate.
Date of Incident: 2nd May 22
Booking Id: NF79RX0FOKFTURU74932

I want the correct cancellation charges to be applied and rest should be refunded as per policy.
Attached is the refund/ Cancellation invoice from Makemytrip
