Gas Heater Bursts into flames - zero response from De'Longhi

I contacted De'Longhi 2 weeks ago and reported that the Heater that I have, literally burst into flames in my home. I had to stick my hands into the flames to turn the gas off to AVOID an explosion. No, it was not the gas bottle, the heater was on, and suddenly a noise went off and i turned around to see the Heater in flames. Based on the reports currently on Hello Peter, they don't seem to respond AT ALL.
