A guy came by and he said he wanted to install Fios for free in case I wanted it and that my building was "on the print". We don't want Fios and have never asked for it. He insisted that it was a free normal install from Verizon and that it wouldn't be turned on unless we called for it. I sent him away anyhow because I don't want a dude mucking around in my electrical closet if I didn't ask for him - and he looked visibly upset and stormed out. I'm assuming this is some kind of scam, right?
