Samsung — AR12TG3BBWK - Product Features not as advertised

I'm Abhishek, and I bought this AC from Samsung app under order ID [protected]. This AC was advertised as having Auto-Clean and Good Sleep feature. When the product got delivered to me and was unboxed, I discovered that these features are not available in this AC, and called up customer care. They told me to wait till product installation, and feature is available and will be explained by technician. The technician post installation denied that he is not aware of product features. I escalated this issue to Samsung product expert team, and they told me that this particular model doesn't have these features. Its been more than 15 days and I have been following up with Samsung, but no response yet on what are they doing to resolve this concern. Samsung's product support is by far the worst I have ever experienced.
I feel cheated for buying a product from a company who can tell lies on product specification page just to sell their product.

I am expecting Samsung to own up to their mistake and compensate me by offering the product which should actually have all these features in actual.
