Reebok India — product damaged within 2 months

Address:	Bangalore, Karnataka, 560075
Website:	reebok india and snapdeal

Hi,
i bought Reebok Boy's Racer K 3 White Lace School shoes from snap deal.
Within 2 months the bottom of the show is cracked. How to get the warranty for this? Is there any complaint id for reebok directly. I would like to get replacement since this is not acceptable. Normally this will not happen in the original product. So i think this could be a duplicate product sold by Snapdeal. I have original bill.
THanks
