My tactil screen stopped working out of nowhere!

I was using my phone and suddenly it started blinking like crazy. Then vertical lines appeared and my tactil screen stopped working. I restarted but nothing would work. Home button or the rest still work is just the screen as if it wont feel my finger! I got this phone in less than a month there is no reason why this could be happening. I am so dissappointed in this products, is not the first time I experience bad things with Apple, my mistake to go again with this.
