Flipkart — Hp Laptop dh 1011tu

There is some spots on the screen for which i need a replacement of the product. Hp polices as well as flipkart policies says that the any electronic item will only get replaced and no refund options is available. But i don't know why the seller is giving only refund option and flipkart is allowing such sellers against their own laws. Also i requested a call back from senior department for may be 10 times bt no call had been received by me.
Must say flipkart and its service both are sick and they need help..
