MakeMyTrip India — Makemytrip refusing free date change according to policy given

Dear Sir/Ma'am.

I have purchased flight ticket from COK to MUM for 3 Jan with PNR number U8CGJA from Makemytrip.
I also have purchased free date change insurance for this flight booking with the ID MTMINFDF[protected].

Now when I tried to prepone or postpone the booking, makemytrip is refusing to honor the agreement since the original Vistara flight was acquired by Air India and changed the flight number of aeroplane.

I contacted Air India and they have confirmed that since insurance was purchased from Makemytrip, the date change penalty needs to be borne by Makemytrip.

But Makemytrip is again asking me to pay penalty for date change.

After multiple service requests it is not done. Tomorrow is flight scheduled date.

Kindly help.
