Query: VERY DANGEROUS

I purchased this dryer about 6 months ago, and today when I was using it it started shooting out sparks. I looked it up on google and this has happened to a lot of people. It's even started shooting out flames and caused house fires when it's just PLUGGED IN and not even turned on. Just don't buy it, its dangerous.
