MakeMyTrip India — international flight ticket cancellation refund

Address:

560086

I had booked a flight ticket (Blr-vie) and had to cancel it since the tourist visa was rejected. I reached out to mmt since they said the visa waiver is applicable. After a few days, i hear back from them stating the airlines have denied it.
On 1st of january, i was told it will be considered as cancellation request and was told about 50% of the money will be refunded.
Its been close to 27 days and have no signs of refund.
Every time i speak to them i have to explain the issue repeatedly. The tickets opened are closed and they say they are still working on it.
I have been trying to follow up on their emails but no response.
The service has been really appalling.
