[Resolved]  Flipkart — used & defective his motherboard sold by flipkart

I ordered one his motherboard from flipkart. Order number od[protected]. After unboxing i found a used motherboard. It was full dirty. After installation it neither detect mouse nor the keyboard. So i called flipkart first for refund. They told this product is not returnable but there is 3 years warranty. So i should contact service center. I followed that. But to my surprise there is no service center of his. They are picking call once after 100 call. Asking to send the board to some unknown address of mumbai. It is all fradulent & nothing else. Flipkart should register genuine products after verification. Can flipkart give me in retun guarantee of repair & return of product if sent to mumbai? Else refund my money.
