Mycro Keratin hair iron

Very disappointed in the hair iron I purchased from Mycro Keratin. The iron has burned my hair so badly that I had to have pieces of my hair cut out, it was so damaged. When I contacted them, all they can ask me for is my proof of warranty! So are they saying that you must spend all this money on a good quality hair iron and after a year you must buy a new one because they can't guarantee that your hair will burn?
