Query: Glass door exploded!

Delonghi has been the worst company to deal with. Not only did they sell me a hazardous appliance but they will not respond to phone calls or emails regarding warranty. The glass door on this oven exploded while I was cooking chicken nuggets. I only had the oven for 3 months when it exploded. I paid over $80 for it and will never buy another Delonghi product again. I'm just grateful my children were not infront of the oven when the glass exploded or there could have been serious injuries.
