MakeMyTrip India — booking id: nn[protected] refund not received

Hi,
Myself naresh peddy. I have booked ethihad flight from brussels to hyderabad (11-apr-2020) and hyderabad to brussels (03- may-2020). Booking id: nn[protected].

Due to covid 19, ethihad air lines cancelled the flight. I requested for the refund for the same. But till now i have not received the refund. I have done the transaction through my hdfc bank credit card. Amount is 70, 254 rs.

I tried so many times calling customer care and i sent mail to "[protected]@makemytrip.com". But till now response or refund from make mytrip.
