MakeMyTrip India — refund for flight tickets booking

I am makemytrip.com double black program user in which we can cancel two tickets in a year.
I already cancelled 2 tickets for this year but when i was checking ticket rates and cancellation policy i got to know that i can book another ticket and that too will be covered under double black cancellation policy. It was written at the time of booking that "this booking is mmtdoubleblack eligible. Book now and get cancellation refund, provided raunak garg is a traveller."
I have screenshots of this as well.
Makemytrip usually have many offers for double black users so after seeing this massage i got confirmed that i can book the tickets and it will be covered under double black and i will get full refund if cancellation.
But now i want to cancel those tickets and makemytrip is not giving me full refund as it was shown on the time of booking.
I booked two tickets with booking idnf[protected] and nf[protected]
Now i want these two tickets to be cancelled and want full refund for both ticket.
Makemytrip is not giving me full refund now.
