You can block even WITHOUT a smart phone. Consider a call blocker, which are available on Amazon for 4000-5000 CENTS. Look at previous posts to get an idea who you're dealing with. I'd say it's a worthless survey that helps callers figure out how to and what to spam you with, along with getting personal and maybe even financial information, too.
Heavy accent. Phone bank. Told the guy to go f himself and get off my phone. Asked for me by name. Nobody, except sales calls calls me by my full first and last name.
