Query: Noisy-dead after 15 days!

In it's defense, this heater put out a lot of heat for its size and kept me very comfortable in a large bedroom. But.....it was noisy from the first time I plugged it in, the noise kept getting worse, the fan started quitting, and a few days later it died. I had only used it for about 2 weeks. I bought it last year as an emergency heater and didn't even take it out of the box until this year, so I can't even get a refund. Basically just a very disappointing rip-off!!!
