Bests & Worsts Reviews from Amazon

I bought this PC less then 3 years and with great surprise the battery expanded and created a dome under the keyboard. I never saw something like this before. and the concern is that the battery could explode and catch fire too. The PC was okay but this latest issue definitely is not a product that Amazon should sell. Where am I getting support for this product that seems a bad workmanship? DO NOT BUY IT
