Air India — Refund for a flight cancelled (never reached its destination)

Address:	New Delhi, Delhi, 110001
Website:	airindia.in and goibibo.com

Flight frm DEL IXB 23rd Jan 2016 departed from delhi and then because of weather disturbances was taken back to delhi ( without landing at Baghdogra) making it a non operating flight eligible for refund ( confirmed from Air India).Air India also gave me a acknowledgement copy for the refund (forwarded to Air India and GOIBIBO) however GOIBIBO claims that Air India is denying the refund for ticket stating that the flight took off. i am tracking the complaint since one n half month now. No refund received for the same.
