Rusted hisense stove

Purchased a hob stove just over one year ago. I am a single person who uses it every two day and it has rust already. It has a terrible smell. I had the worst time getting hold of hisense only for them to be of no assistance telling me the warranty doesn't cover such. It is a health hazard with rust and the smell is terrible. I am shocked that a product that is suppose to last many years has turned out to be such a disappointment. Be careful when purchasing from hisense
