Query: Bad purchase, doesn't last

Buyer beware! While it may work fine at first, it will break in no time! I purchased this laptop less than a year ago, and although I was extremely careful and gentle with it, it is completely useless right now. The screen keeps fading, and only extreme and constant pressure on the screen at a certain angle will bring back the content. However, it's not possible to type and work on it while putting pressure at the same time. So I'm left with no laptop in the middle of a college course :( I tried contacting the seller over a week ago, and haven't received a response at all. This is by far my worst purchase ever!!
