Ibibo Group / Goibibo — To get refund back

I am Prashant M Suryavanshi, customer of Goibibo, but I'm totally disappointed by the service now, I booked my flight from Ahmedabad to Nasik for 21-November-2021, but flight was cancelled by airline due to some operational issues, and I haven't got my refund yet. It was more than a three week and still I haven't got any confirmation from Goibibo side but I was informed by trujet airline to collect my refund from my partner app. The main issue is I could not find any support feature to enquiry regarding this in their webb/app. So please kindly see to this issues and guide me through.
