Asus India — asus e202s

I bought asus e202s two months back from one of the asus authorized distributor in coimbatore for business trip. Buy it faced lot of difficulty in handling the product. Its not user friendly and the process is very slow, i contacted the seller and discussed about the same. But the refuse to exchange the product and didn't provide right support. At the time of purchase they very much recommend this product but now they told the performance of this product is limited. We are ready to pay difference amount and upgrade the product. Kindly do the needful.
