ShopClues.com — Cheated on name of 100% cashback

Address:

Hyderabad, Andhra Pradesh

I have made an order for 816 Rs on 14 Aug 2015, 04:36 PM (conditions was order should be more then 690 Rs for 100% cashBack on Independence Day sale offer), now shopclues have cancelled my two products for Rs. 157(due to now out of stock-but the website says the products are in stock).
when I called customer care for this, they said me that you wont be getting 100% cash back as there is a product cancelled, and your total amount is less then 690.(I HAVE NOT CANCELLED you have cancelled),
Clearly there website says that the products are available on there website.
even shopclues terms and conditions for independence day offer also doesnt shows any thing regarding cancellation on order value.
This is a clear case of cheating on customers.
Kindly refund my complete amount with penalty of cheating and troubling me.
I HAVE BEEN CHEATED BY SHOPCLUES...
