zavian fashion - Defective product delivered

I was looking for a spirometer for lung exercise on flipkart. I saw one of Romsons and ordered it. The total price was Rs ***. When the opened the parcel I found that the product was, first of all, not of Romsons and second of all, defective. Now, the product is showing a no return policy. For a second if we stick to the no-return policy, it is important to note that as per the website, the no-return policy is for the product that they show there and not on any stupid product that they deliver in the name of delivering the represntational product.
