Bests & Worsts Reviews from Amazon

This heater worked great for 4 months then the plug got so hot it melted my outlet and could have started a fire. I have emailed the company with no response. I try to go to their website and it’s no longer a website. Not sure how this can be fixed. Not only was it still under warranty, I also got a 2 year thru amazon, but can’t use it cause the other one is still in place, but I can’t get ahold of the company. I want my money back.
