Rediff.com — delivery of damaged product and now no refund of my money/ exchange of product

I ordered handicraft from rediff.com. when it was delivered to me it was damaged and I informed them on the same day is 26 step 2014. today its 15 Oct 2014 and no step have been taken by them to either exchange the product or refund my money. I have called them many times but the customer care people are not at all responsible and every time I call them they say no such request have been registered. I have all the records of phone calls and e mails sent to them. I want a strict action against them. order no is 10428149. this is such a fraud that they take money and then don't give the product in good condition. m not paying for a damaged product.
