Hey, so first off there is a way to disable the touch screen I don't remember specifically how to do it but a quick search will lead you to an answer.
Unfortunately Acer will not pay out for selling you a defective product. They will send you in a loop of customer service call centers and tell you that any physical damage is not their fault despite the fact that a design flaw should be a considered a defect. Acer does not care about their customers, after they get their money you're on your own. It's something to keep in mind for the future but for now I would look into getting it repaired by a third party repair center to have the screen replaced for about $100. Best of luck friend.
