MakeMyTrip India — no response from make my trip team on refund and deferred holiday trip due to sudden death of my family member

Booking id: nl[protected]
I booked a himachal package 2n shimla+3n manali on 29 september, 2017 from 02 october to 06 october, 2017. But due to sudden demise of my uncle i contacted make my trip team to postpone my trip to some other date. And i also wished to know about the refund policy. They told they will get back to me within 24-48 hours. But its been 03 days no response i have got. I booked the package amounting 61, 673. I have been calling make my trip helpline no. Every now and then, they tell they are forwarding my case to concerned authorities, but no response is being given. My make my trip experience is very frustrating. Please help me resolve the issue.
