GoAir — Cancelled flight ticket not refunded

My flight from Patna to Ahmedabad- Flight # G8 8034 of 5th June 2021 was cancelled by the GoAir. First I received a flight delay message and later, was informed that the flight is cancelled. There is no information from GoAir when will the money be refunded. I have written two reminder emails to their customer care but yet to receive a reply till today (29th June 2021).

How can Aviation Authority of India allow them to keep booking tickets and let them fly inspite of over thousand such complaints! They have to be held accountable for such serious offence.
