Consumer Redressal

Sir , I ordered six pieces of night wear set and received on 13 Jan 2014 from rediff online shopping. From that date I am calling to rediff shopping for return of product and refund of value of product due to its poor quality, colour is different and small size. Till the date they are asking for product photos and bill photo. I sent so may times from receiving of product. They saying we will return the product and and will refund my money for that product. But today when I called them they said that product is out of warranty so neither we will replace nor will refund the money. So please help me in this regard. Thank you.
