I booked the flight from PAT-BLR ( PNR - Z8H82Z, Booking Reference - REF[protected] via Travolook. It was cancelled by goAir on 15/6/21 06:04pm IST.
goAir refunded the amount to Travolook on 02/07/21 and shared the mail to me.
However, Travolook is repeatedly telling me that they haven't received it yet. Most of the times, they will put my call on hold and then disconnect it.
