EXPLODING PANEL! Vivint panel started heating up. I could hear weird noises and feel the wall getting warm. When I called, they said it was probably something in my house and they could send a tech to check it out but it would cost me a $49 service charge. I agreed to pay it and they said they couldn't get me a tech till the next week. 3 days later, the panel burst into flames and would have burnt my house down if I didn't use my fire extinguisher. It was the battery inside the panel that started swelling and eventually caused a fire. They referred me to Home Damage who offered me a $500 settlement and wanted me to sign a Release Form promising not to sue them or talk about what happened ever again. I had a contractor quote the job at over $1200 but Vivint only offered me $500 and a new panel. When I threatened to report them to the Attorney General and the BBB, the rep in Home Damage laughed and said "Have fun with that." Unbelievable.
