MakeMyTrip India — Refund not received Flight Booking id NN7O9XQU8S2ZZV7S2832

I had booked a flight from Delhi to London Heathrow for 18th March 2023 and paid INR 54983
On March 13th, i requested for cancellation and the customer care told me the about the cancellation charges which are also mentioned on the invoice as INR 15566 (airline charges) and INR 649 (MMT charges)
I have been issued ZERO refund. Conveniently MMT doesnt recognise my booking anymore when i am trying to get in touch with customer care and do not have an email support either
Unethical and fraud service. fellow customers beware
