MakeMyTrip India — Refund of Jet Airways flight

I am Suchika Naithani, My flight dated 26th April 2019 was cancelled by Jet Airways saying that MMT will refund the amount but I have not got the refund of ₹6, 251 yet.
After so many rounds of follow-up with both Make my trip and Jet-airways, I haven't got my refund back.
