MakeMyTrip India — Refund processed by airlines but not paid my MakeMyTrip

Website:

www.makemytrip.com

Despite multiple emails, MakeMyTrip is not paying me the refund for the amount I paid to book flight ticket which was refunded by the airline (Indigo) as flight was cancelled. It has been more than 6months now. Their customer care contact numbers are useless and leads back to the website which has no option to raise an issue.
