Makemytrip india Pvt Ltd - Makemytrip not refunding amount for holiday package after flight cancellation

I booked a holiday package for Mauritius (BookingID#NL*************) with makemytrip (one of the agents in Pune) on Feb **th ****. The holiday was planned from **th June **** to **th June ****. Total package amount was rupees ******/- and I booked this trip paying more than half of the amount which is rupees *****/-.
So basically this booking was not done from my account. It was done from the agents account.

Due to this pandemic, I received a cancellation SMS on my mobile (on May**th ****) for both onward and toward journeys. The SMS stated "Due to suspension of flights till **th June****, MK***/**th June and MK***/**th June has been cancelled. Please contact your travel agency".

I informed makemytrip about this and asked them for refund of my booking amount, but I have been given reasons like "Airline is grounded and not refunding money" so we cannot refund you anything at this moment. I have not been shown any proofs regarding this statement. Even I was not shared the PNR of the ticket so I could check myself.

From **th May **** till today, I am constantly chasing up with makemytrip over email and calls, asking for refunds and I receive no positive response from them.

My ***** rupees is stuck with makemytrip during this critical situation.
This company is a complete fraud and holding my money since * year.
