GoAir — Processing of refund of my cancelled flights

Address:

Mumbai

I am horrified at the kind of service goair provides, to say the least. I had a booking in flight g8-2601 on the 5th of june 2020 from mumbai to nagpur. My pnr is iblsqa. I got a message from go-air on the 3rd of june that my flight was cancelled and that i will get a full refund if i call on these 2 useless numbers given below
[protected] and
[protected]
I understand that due to the pandemic situation, they may be getting a huge volume of calls, but it can't be the case that the numbers are never reachable!!!
I even sent a e-mail on the email id [protected]@goair.in and i was told that one of their agents would contact me, but no one contacted me.. I again sent a mail 17 hours before the scheduled departure of my flight. But, as expected, no response.
I tried filing for a refund on goair website, but there is no option of refund on their website. Why don't they have an option of refund when they know that it's impossible to approach them i any which way!!!
I then rescheduled my flight for the 9th of june as that was the only option to make sure that my money doesn't go waste. But, voila!! I got an automated call which told me that this flight was cancelled too!!
Now, my web check-in is also stuck halfway, and it is asking me to contact the above 2 useless numbers to de-select my seats!! I mean, why???!!!
Pathetic service i have ever seen. Just guzzling up people's hard earned money. Don't ever travel by goair.. They are fraudsters!!
One more thing, i was also supposed to get 1048/- rs. As a difference of fare when i rescheduled my flight. There is no clarity given as to how would i get back this amount??
