Refund issue

I had ordered an item from Flipkart and made the payment through my credit card. After some days, the order was automatically cancelled. Since the order was cancelled, the company was required to refund my payment. Flipkart processed the refund as a credit to my credit card, but my credit card has since been closed, so I am unable to receive the refund in that account. I requested them to instead refund the amount directly to my bank account number, but Flipkart is denying this request and insisting on crediting the closed credit card. I now demand that Flipkart refund my payment amount to my bank account, since the credit card originally used is no longer active and cannot receive the credit.
