GoAir — no refund on flight cancellation by airlines

Pnr-vy938t, date of departure-23/03/2020
Flight from ccu to blr was cancelled by airlines. I received a mail saying i am eligible for full refund. Haven’t received any refund. The helpline numbers are not reachable, not getting a single answer on the mails sent.
Had booked via easemytrip but received call which confirmed goair will be refunding the amount. That number is coming switched ever since
