MakeMyTrip India — MakeMyTrip India Refund amount not received for cancelled flight

Hi,
This is regarding my Makemytrip flight booking NF[protected].
On 25th Nov'20 got an intimation from Indigo that they have cancelled the flights 6E-6175 for 4th Jan'21 from Mumbai to Mangalore and 6E-459 for 11th Jan'21 from Mangalore to Mumbai.

I got a confirmation from Indigo that the refund of Rs.22713/- has been processed and credited to MakeMyTrip and they provided the below reference nos. that confirm the amount being credited to MMT.

PNR: GJ9BFW[protected],[protected]
PNR: AN18FK[protected],[protected]

MakeMyTrip mobile app and website show that the amount has been refunded but, it still does not reflect on my Credit Card or Bank Statement.
I even locked a complaint with this, reference no. for which is[protected]. However the complaint was closed without any resolution.

I have been trying to reach MMT on their email ID, Customer Care nos. Twitter but there is no response.

Total amount yet to be refunded to me after deductions by MMT is Rs.18710/-

Kindly provide me a response as to why the amount has not been refunded till now and what is being done to address the issue.
