EaseMyTrip.com — refund not processed even after several requests and emails

Booked domestic flight ticket on march 23rd 2020 for march 29th 2020 for an amount of inr5139, due to the flight cancellations by the government, i have rescheduled the flight to april 15, 2020 for an amount of inr3596. The indigo airlines have refunded this difference amount to easemytrip. But, till date, the easemytrip is not at all refunding this amount to me even after several requests. There is no tele customer care support or even no chat support. I have send several emails to them. Every time they are giving different responses by different customer care executives. One time they are saying that the amount will be refunded with in 10-12 days. I too waited more that that. After that, some is replying me that i have to wait for another 10-15 days. Another one says that, they will refund once my travel is completed. But, the indigo customer care executive says that this difference amount has to be paid by easemytrip to the customer immediately. No need to delay. Even i forwarded the chat transcript with indigo to the easemytrip, they are responding like i have to wait till my travel to be completed.
Also, i have asked them whether i can use this amount of inr1344 for any other bookings, they are not responding for that query.
Finally, i have understood that, using this covid-19 outbreak opportunity, they are keeping the amount with them for some more days. This is absolutely a cheating.

Kindly take necessary action against them.
