Goibibo - Refund amount not recieved

I had a flight schedule from Blr-Sxr For **th April **** Booked Via Goibibo.Com Per Pnr #: WPHYXX .I Received Email From Indigo Airlines , saying, your flight schedule Is changed and Offered to Choose other flight Or cancel at No Charges on **th March **** along with a link to which I followed and Cancelled the flight. The Amount Was refunded in full by Indigo Airlines to the agency with Confirmation Email . I Cancelled Via Goibibo.Com as per process as well and It Is showing Refund Under Process from Past ** days. After doing a followup Via tweet, they are replying saying , we will get you back and Some times they say It Will refunded as credit note. I had explained them number of times, saying, It was not Cancelled due to covid reason but becuase of flight change with option given by airlines to accept or cancel at no extra charges and with full refund if cancelled , confimration from airlines.
I need a full refund of amount in my bank account from goibibo , who is turning deaf to my requests. The refund is already processed by Indigo airlines to Goibibo but goibibo is not refunding it in my bank account. Please help in getting my money back
