These guys keep calling me. Somehow they got a hold of my cell phone number - if I ever find out who sold it to them, that person/company is in for a world of hurt. I don't always answer my cell, and they were calling me two or three times per day. Never left a voicemail. I finally called the number yesterday and discovered it is Vivint Security. They said they would take me off their list. A few hours later, they called (I missed it). Then today, they called again. I called them right back and had a massive fit. They wouldn't tell me how they got my number. I only give my number to those I do business with, so I am ticked off. If these guys call me again, I am going to get some serious rage on.
