GoAirlines - GoAir not refunding for cancelled flight

I have booked a ticket from Varanasi to New Delhi on March ** ****, to get my mother and sister with her * months baby back to Delhi. They are alone at home in Varanasi with no food and all or anyone to take care of. I made a flight ticket for April **' **** after the Corona Lockdown was supposed to be lift. Unfortunately, I got a mail from GoAir on April ** that they had cancelled the flight now( why even they took the booking in the first place then if they were not so sure), and they are forcing me to book the ticket on any other future date with SAME passengers. Thats it. They won't reply to my mail on this, their customer care not picking phone, they don't even taking any future booking not have they provided any other date or how they going to resolve this issue.
Atleast make a flight ticket for me for earliest flight date possible, with NO EXTRA charges as they have told in their mail, or else just refund my full money back so I can plan some alternative.
They are telling to cancel the booking and convert to some credit shell BS so as to use it in future and that too FOR THE SAME ORIGINAL PASSENGERS. Ridiculous.
