The flight was canceled by goair. We were required to go back home from the hyderabad airport. We submitted our case for refund as per the guideline provided in an automated call from goair well within the time. We emailed on 23rd march 2020 itself to claim the refund. We received an automated reply with the service request number - g[protected] for passenger poojan and service request number - g[protected] and g[protected]. We have carried out a follow up on 31st march. We also tried to reach goair on their customer care number[protected] / +[protected] provided on their website (https://www.goair.in/customer-care-number).
