MakeMyTrip India — Airlines cancelled flight and Refund of Money from MMT not done yet

Spice Jet refunded the amount to MakemyTrip but Makemytrip has not made any refund to me till now (more than 3 months). Flight has been cancelled by Spicejet due to their operational reasons and this is before lockdown i.e., on March 13 2020.

I Kindly request Makemytrip to contact me as early as possible and make refund at the earliest

How can i contact customer care through Phone no.?
I am unable to raise a claim from my booking id.
I always get a message "Sorry, Something went wrong.
We are not able to process your request due to some technical issue. Please try again. In case you are facing this error repeatedly, please call us at [protected], [protected]." and when i contact through these nos. they again say to visit web forum and message appears again. Being a top agent in bookings how can they do this???
