GoAir — refund of cancelled flight by goair

I booked go air flight g8-720 and g8-697 for my travel plan in 04 april 2020 but due to all india lockdown and corona crisis my flight has been cancelled by airline and i didn’t receive my refund. As per dgca notification airlines have to refund the whole booking amount without deducting any amount to passengers but after numerous conversations with go air customer support, i didn’t get my refund. As informed by go air customer support my pnr is saved till 31.12.2020 and i can reschedule my flight without any charges. However, now i am planning to reschedule my flight and i am unable to update/reschedule the flight date to october 30, 2020. Kindly do the needful on urgent basis. Contact me on [protected]
