Vivint Home Security System reviews and complaints

I bought a home with a vinit security system already installed. In the past few days, I have tried to have the alarm system activated. I made an appointment for 3/3/2022 and Vinit's installers were to arrived between 4 and 8 pm. They did arrive early. There were two muscular men that arrived that easily intimiated me. They first asked for my code, I did have one code but not the master codes. I reluctantly surrendered the code. One of tech typed the information into the control panel of the security system and into his tablet, while the other roamed the house observed all of its belongings. This made me feel very uncomfortable and the he brought me his tablet and coerced me to sign a contract and consent to digital signatures. I requested a copy of the contract, I had called the company earlier and was told there was no contract required because I owned the equipment. The seasoned tech also told me that I would have to submit to a video interview to see if I was mentally compent. I refused to have my personal information stored in their database. I spoke with several reps from Vinit and was not able to get a copy until I spoke with Ethan. He provided copies and told me we could activate the system over the phone. I did sign the contract with the understanding that the system would be activated at 7:30p. I called after the tech failed to call to set up the installation. I was told that the system was not going to be activated according to Ethan's instructions. I now no longer have access to the system. The system controls the front door lock and is able to listen to all conversations in my home. Vinit has has total control of the cameras, passwords, codes, and the front door lock. I do not feel comfortable with a security system that costs $50 to be used for spying on the customer.
