UNSAFE Electric Blankets

I have an electric blanket from Carmen Elektra. It is 3 years old. Whilst asleep I awoke to the smell of some and both the switches were smoking. These units are not safe and the company does not offer any feedback or help in any way. I have called into their offices and I have been told that they simply cannot supply new switches as the product has been discontinued. The staff are rude, arrogant and do not offer any solutions or explanations. I see it as winter has arrived again and they are too busy making money to care about post sales service. - Are these products safe? - Could my wife and I burned in our sleep? - Will this company take responsibilty for the unsafe product?
