MakeMyTrip India — Indigo cancelled flight and refunded amount, but makemytrip not refunding amount

Sir, This is regarding booking id in makemytrip NF[protected] . It comprises of two flights Chennai to coimbatore and Coimbatore to chennai. The flight form coimbatore to chennai was cancelled due to covid and kept in credit shell by Indigo. But later due to government regulations they refunded the amount to Makemytrip on July 16th. I am unable to claim refund from Makemytrip as they have given no option there in their website. I am unable to reach any customer care. They are so irresponsible. I am hitting a roadblock I need my refund asap.
