GoAir — Regarding refund of a flight rescheduled by airline

Address:

SG-88 1st Floor Shastri Nagar Ghaziabad

I booked a flight of go air for 10/08/2020 from delhi to bombay. I received a message from the airline the flight has been rescheduled for 11/08/2020 (Message received): as i have to go on 10/08/2020 due to some urgency, the schedule for 11/08/2020 is useless for me. Therefore i booked another flight ticket for bombay and get my job done. The details are as follows:

Passenger name : yusuf
Origin : delhi
Destination: bombay
Date of journey: 10/08/2020
Flight no.: g8-336
Airline pnr: s4ygsy

As you could notice the date of travel was 10/08/2020 and i have mail for refund on 09/08/2020. But the airline is not responding positively till 14/08/2020.
