MakeMyTrip India — Hotel booking changed on last minute and allocated a poor hotel

We have booked for Bellichukki homestay through make my trip. I have made the complete payment inclusive for hotel stay, breakfast and dinner in make my trip..Next day I got the call from the property owner as proper is already full and they are unable to provide the room for us. Inspite I tried makemytrip multiple times for cancellation and for getting refund ...makemytrip have not considered my issue, though nothing is wrong from my side...at last, as I am highly frustrated on makemy trip, they arranged for a conference call. Property owner told he can arrange for alternate good hotel. When I made a checkin there, we noticed it is in very poor condition, there is no fan, no TV, no attached restroom, blankets are dirty, rooms are not cleaned, we could see frogs, spider, cockroach roaming around. With no other option we stayed there and we has sleepless nights. Please help in getting partial refund on my booking(*MakeMytrip Booking ID*: NH[protected]
