Refunds are always done in the original mode of payment. 

For online paid orders, a refund will be given via our payment gateway to the card from which the payment was made (in case of payments done online). For payments done via Cash on Delivery, we will ask for your bank account details and the payment will be made via NEFT. And for the order placed using store credits, the refunds will be done in the form of store credit only. 

Before raising a request, you can check if you are eligible for a refund here
