EaseMyTrip.com — Easemytrip not providing refund

I had a booking for indigo flight from bom to trv on 16 june. I had also taken the emt insurance. However the airlines cancelled the flight. Now emt is not refunding the insurance amount + deducting ticket amount. Their customer support is also very pathetic and harsh. Flight details: pnr: nde23l booking date: 16-june 6e 975 bom - trv amount: 7990 ticket price emt insurance : 3398 extra please do the needful to get the full refund as airline had cancelled the flight
