I ordered a ₹600 dress from Little Box on 4th September. The package was returned, but I have not action and help me get my ₹600 refund

I would like to file a consumer complaint against Little Box regarding a refund issue. I placed an order for a dress worth ₹600 on 4th September. At the time of delivery, I was out of station and could not receive the package. The delivery was attempted, and the package was subsequently taken back/returned by the delivery team. Since the order was not delivered to me, I expected the ₹600 amount to be refunded. However, despite the return of the package, I have not received the refund in my account till date. I request the Consumer Support authorities to look into this matter and take appropriate action against Little Box for failing to process my refund. I also request that the ₹600 refund be processed at the earliest and that the company be directed to provide a proper explanation for the delay.
