MakeMyTrip India — not provide gst invoice

Hi,
I have made a booking in the lalit ashok
Bangalore, through booking id nh[protected], i have already provided gst no. While booking the hotel.
I informed make my trip through mail on 3rd december that i want gst invoice, but after series if follow ups, so many mails communication still after 27 days they have no provided gst invoice. Every time they say "please wait for 48 hrs, but still after 27 days no invoice provided.
I just fed up from make my trip service.
Even today they closed my previous refrence id no. And alot me new refrence id for the same issue. I dont know they are making fool of their customer or what.
