Flipkart — ordered 2 products but received only 1 and which is defective

I ordered 2- wireless mouse order id: (0d[protected] but received only one mouse in packet and the mouse received is not work properly. I try to contact flipkart customer support as well as 2gud customer support. The 2 gud customer support not responding my emails and they have no any tollfree number. When i try to contact flipkart the customer executive of flipkart give one answer that 2gud is different plateform and flipkart is different. If 2gud is different from flipkart then why flipkart merges 2gud in his application. The 2gud customer support is not responding of my emails. If my problem is not resolved then i will order 100-500 products from different account on flikart and cancel all the products at my doorsteps. I request to flipkart and 2gud to provide good customer support otherwise the future of this firm also like snapdeal. Thanks i hope you resolve my problem as soon as possile.
