GoAir — cancellation refund not received

Sir,

My flight pnr jfj2qr goair flight g8-421 from hyderabad (Hyd) to new delhi (Del) on[protected] at 05:35 hrs got cancelled from the airport carrier's end. I tried reaching on the customer care number but there was no answer. I all the way reached the airport 3 days before the departure and informed the staff about the same. They said they have initiated the full refund, but till now the money hasn't been received. I have made a fresh complaint over phone too but futile. Kindly do the needful. This isn't expected from a reputed airline service

Regards
