The Mobile Store — Misleading information

I have placed an ordered of Micromax Canvas Hd A116 smartphone with extended warranty from http://www.themobilestore.in/ on 24-Sept-2013. Total price of both the products was Rs. 13848/- I have applied a coupon code and got discount of Rs 1000, coupon code was issued by http://www.themobilestore.in/ in some earlier promotional offer through facebook. In there website, where product information was shown, I was getting a message in highlighted color that if I pay through SBI Debit/Credit I can avail 8% discount. message was as follows - "FLAT 8% DISCOUNT on all State Bank Credit and Debit Cards!! Discount will be shown on payment page once you enter your card details and click Pay Now. Prices valid only on the website." I have paid total sum of Rs 11820.16 after applying coupon code & also paying rest via SBI Debit card and received order confirmation mail from their side. but later on 26-Sept, I received mail from them that the order is cancelled. To clarify the reason for cancellation when I spoke to their customer care executive, the person told me that since I availed two discount offer they cancelled the order. Now the issue is I was completely unaware of the Terms & Condition whatsoever regarding my purchase because during the entire process of selecting/confirming/paying the order there was no mention of such conditions. Although, they have already refunded the amount which I paid to them, but I felt bluffed & wasted my time over their useless service claims. If I knew at the time of purchase that, this condition may arrive, I would never go for buying by availing both discounts. Regards,
