MakeMyTrip India — Refund not received and they are lying that they have reflected that they have processed the refund.

I have cancelled a flight from mmt and they were supposed to refund me Rs.1678, but till now I haven't received any refund. They were supposed to reflect it in my credit card but when I checked my credit card statement I haven't received the refund and according to them (as shown by their website) they have reflected in my account but till now I haven't received it. I had many a times tried to contact them but they always redirect me to their website. Therefore I request you to please process my refund as soon as possible. They could help us a lot in this period of lockdown. Therefore I am here attaching all the details of the tickets and some screenshot.
