Nike India — Not able to cancel an order on Nike India

I have placed an order on Nike India and after some time due to some reasons I wanted to cancel the order but there was no cancellation option and customer support also denied canceling the order despite the fact I was canceling the order within 4 hours of order execution and the product wasn't even dispatched.
The company's agent is citing a 30-minute canceling policy which is not shown during order placement and the article related to policy is also not available on the Nike India website. I want a full refund from the company but they are still forcing me to get this product and later return it which is very time-consuming as it takes more than 20 days for product delivery and another 20 or 30 days for product return and refund.
I even offered to get a refund in Nike credits so that I can order a new product they denied. Please help with this issue they are completely taking the rights of customers.
