Seller is selling US imported laptop for which warrenty in India is not available. Seller was very unresponsive, picked call once after more than 20 attempts. Amazon also seemed helpless and non responsive. After escalating the concern through various channels like twitter and emails Amazon was of no help except allowing to return the laptop after 2 months.Dell also disowned the product and their esclation team clearly told that this is not a valid product for sale in India so can't help much.Amazon should also understand that it's not just the money which is invested in a high value purchase like a laptop, but lot of time and energy is also invested. So just returning and refund don't serve the purpose.Tried a lot from every side, dell, Amazon but all the efforts could result in a refund after 2 months. Very horrible experience.
