Ease my trip com - GST Invoice not issued for the amount charges

Myself and Sh. Arun Kumar travelled with following flight details
Air PNR:- **EJ** (Invoice from Easemytrip attached), Ticket Number:- ************* / *************

Ease my trip charged for Airfare Rs ****/-, taxes Rs ***/-, K* (airport fee) Rs ***/- and as a service provider a service fee of Rs ***/- each. on this a discount of Rs *** was provided on each ticket. We had paid an amount of Rs *****/- for two tickets.

On airlines website when we check for an invoice we get a GST invoice of Rs ****/- per head only. ie Rs. *****/- for two persons.
Rs *** is the service charges for which easemytrip should provide a GST invoice and balance amount Rs. *****/- GST invoice we were expecting from Airline.

Neither we are getting the GST invoice (attached invoice from easemytrip did mention the GST amount) from ease my trip not getting it from the airline.

I have taken up so many times with the customercare of easemytrip but could not get a solution.
We are feeling cheated after getting a ticket booked from easemytrip.

Please provide the GST invoice of the amount paid by us as we understand that GST must have been paid by easemy trip on the amount.
