Snapdeal — product quality worst

I had purchased Sai Arpan Set Of 4 Double Bed Sheets & 8 Pillow Covers -10 Pcs Set with order id [protected] on 6 Dec 2013 from Snapdeal through online shopping. I received the product on 8 dec & I used 1 bedsheet. After 2 days I washed it & found it totally faded, it was red colour bedsheet & after washing colour was gone & it had white patches as it was one time use. immediately I called snapdeal & they said as it was washed it cannot be replaced but it is a combo pack & you have 3 so it would be considered .But now they are denying.I told them give me sellers contact number so that I can speak with him & tell to use his product in his house so that he will come to know .But nothing they are doing. my request id with snapdeal is #4284724.I have sent them photo of the bedsheet also as they required. Snapdeal's return policy is not fair & they promote third class products which can be used only once so beware guys with Snapdeal.
