Flipkart - Product not picked up

I have order for wildcraft sweatshirt but the product is not as upto the mark therefore I return the product which was delivered * days later from the delivery date. After five days from the the date of requesting for return I called them that my product has not picked therefore again I told them and the told that my issue is highlighted and a wishmaster has been assigned but finally my product was not pick up and my return request has been cancelled without any reason.Now they are telling that they cannot return my product as the return policy has ended.
