Since joining Optery, my robo calls have stopped. I was getting six to ten a day, every day. Once subscribed, they have stopped. Been over six months. Money well spent. The amount of websites that listed my personal information was totally unknown to me. Wow, there's a lot of companies that buy your information. Have even used their report marketers service to report the few companies that got through their scans. Best money I ever spent, just for a silent phone.
