Go Air — Refund of tickets

Address:

Mumbai

I’m writing on behalf of mr krishna das who had a ticket booked from calcutta to mumbai and was supposed to fly on the 22nd of march. His pnr is w96dgj and the flight number was g[protected].
The lockdown was announced on that date and hence the flight was cancelled and he couldn’t fly back.
As i’m checking on go air website there are no flights from calcutta to mumbai in the coming days, nor is there any information available.
I’ve been trying to contact the customer care but there has been absolutely no response in-spite of being on hold for over 2 hours.
Please let me know how to proceed as the passenger wants to fly back asap.
I have sent this mail on 17th june. There has been no response. Please help.

Looking forward to hearing from you.
