GoAir — Refund issue and cancellation of ticket without prior notice

I booked a flight ticket with goair airlines for 2nd of july. They cancelled the flight (G8-231) hours before flying.
They are not even providing us refunds.
We have to plead them for our own money.
I just don't understand, why the heck i have to plead for my own money.
Just because i have paid for services, which you haven't provided, my money is yours. Goair has got no right to lein on my money.
Goair has pathetic customer support as well. They have never responded to anyone. I am not alone, there are numerous people out there on every social media, but still no actions has been taken.
I am however sharing my details..
