Ibibo Group / Goibibo — Refund not provided for Airline Cancelled Flight

I have booked a flight ticket from Delhi to Pune through Goibibo on 1st July. On 2nd July, I email/SMS from Goibibo that airline cancelled the flight due to operational reasons but never got any notification email from Air India. The mail had suggested to go ahead raise request for refund and I had raised refund on 2nd July itself. It is been more than a month and the refund is yet to intiated and I had to pay bill for the amount since I had used Credit Card Payment. When checked with Goibibo, they are asking for airline document which I never got as all i got is Goibibo mail for cancellation notification of flight. Can you please esclate the issue to intiate refund at the earliest.
