Housefull International — Damaged Product - no replacement and no refund :(

Unfortunately I happen to be one of those unlucky souls who opted to buy furniture from Housefull Furniture. I had placed an order for 2 KU
DELL SLATED 4D SHOERACK (HDC NO : 9954/2014/590)on Jul 27 2014 online and made the payment of 12000/-. The items were delivered promptly on 27th as promised. The packages were opened by the person who came to aseemble them. On opening, it was found that one item had scratches and the other one had a damaged part. The assembly person himself had suggested that I ask for a replacement as both the pieces had damages in it. On contacting the customer care no[protected], I was assured that the damaged parts will be replaced with brand new ones. As I didn't get any further update from them after 2 days, I called them on 1st August. I was told that someone would come from the Chennai showroom and replace the item on 3rd August. The Chennai showroom people contacted me and I asked them to come on 4th as I had some prior commitment, to which they agreed. They assured that they would come on 4th evening. On calling the Chennai porur showroom on 4th evening, I was told that theywon't be coming as I had bought the items online and hence they are not responsible.
I sent a mail to [protected]@housefull.co.in updating the events but never got any reply. Again I contacted the customer care and a lady named Sylvia said that they don't have similar products in the Chennai showrooms and that she would get back to me in 2 days. After a lot of failed attempts, I managed to get her online. She told me that they don't have any more pieces and that I should choose some other product of theirs, and also that they won't refund the money. I do not want to try my luck again as I am already regretting the decision of choosing such a company with a bad customer service.
Request you to kindly help me out with the issue as 12000/- is not a meagre sum that one would be willing to compromise on.
