GoAir — Without any information flight with PNR -YF3F8U and Flight No-G8-873 got cancelled and no refund has been given till date..

Had booked two tickets in name of chumki naha and Anita naha on 2nd june'2020 from Bangalore to Ranchi with PNR YF3F8U and fight no was G8-873, go air had cancelled the flight for that date and till date no refund has been given to me.
Had taken several follow-ups since then also wrote several reminder mails to them still no response.
On 9th aug '2020 as per the advise of one of the representative I had also raised a service request no-G[protected]/01268601 and it was said that matter will be resolved within next 5-7 working days.
Now it has been almost 10months I'm writing reminder mails but I'm not receiving any response and my matter is still pending for refund.
Go air is cheating their customers.
Had considered below mentioned mail ID's for writing reminder mails.
