Consumer Redressal

This is in reference to my order # 3159 on www.shoppingnsaving.com, Yesterday I got a call from a person with mobile number 7090701025 has cheated to me. He had told me that there is a heavy discount on certain electronic which I can avail till 8 pm on 13.05.15 only and I can buy any items till 90% discounts. I have placed 2 ordered on 25th April . and after that I noticed like something is wrong. I make return request of this order on 2nd May and get return id no. 74 & 75 . After some time I called Mr. Ajit Kumar from www.shoppingnsaving.com to know the status of my return . He just surprised me while saying that that was the contest and you got the reward points and you can not get the money back. Their executives are lying to customers and this is called fraud. They are directly cheating the customers and this shouldn't be acceptable or tolerated. Plz help me out
