Vivint Smart Home misrepresented services and failed to provide essential equipment and support, leaving my household without a functioning thermostat and without heating or air conditioning for over a week.Vivint Smart Home contacted me under the pretense of a promotional visit for solar panels. During the visit, the technician offered to install a free smart thermostat as part of the home security system installation.At no point did the technician disclose that he would rewire my home's thermostat to function exclusively with Vivint equipment, effectively disabling my ability to use any standard thermostat on the market.On October 23, 2025, my thermostat completely stopped working -- the display went blank, and I was unable to control temperature, view settings, or use heating/cooling. I immediately contacted Vivint technical support, who directed me to Lowe's/Vivint product support to determine a replacement.I was informed that no compatible replacements were available in stores in Arkansas and that one would need to be mailed to me, with a 5-7 business day shipping delay. I requested expedited or overnight shipping given the circumstances (no functioning climate control), but was told this was not possible.On Friday, October 24, 2025, I received a DHL eCommerce tracking number (#9261290339708357415664) -- however, only the shipping label was created, and the package was never shipped.When I contacted Vivint on Saturday, October 25, they confirmed the warehouse was closed on weekends and promised to follow up Monday to ensure shipment.By Wednesday, October 29, 2025, the package still had not shipped. Vivint representatives falsely claimed it was "in transit," while DHL confirmed they never received the package.This lack of transparency, accountability, and urgency is completely unacceptable. My family has been left without heating or cooling for over a week, all due to Vivint's equipment, poor communication, and deceptive installation practices. read more
