Ibibo Group / Goibibo — Free flight cancellation

I had booked my flight from Goibibo app, but the airline cancelled it for some reason. The airline has accepted my request of full refund on my flight from Delhi to Pune (PNR Number - W4J3WW) scheduled for 27/11/2020.
But your Goibibo app has yet to give me any information about it, the app has not been updated about my flight cancellation and the helpline numbers are being useless.
