That "this is your third and final reminder" type calls are for any and every type of product, it seems.
I and my neighbors all get tons of robocalls and other junk calls, even though robocalls are illegal in my state. I don't like that they ask if it's me by name, because I have no desire to confirm and thereby guarantee that I'll be bugged in the future and that my number will be sold on to well beyond whoever is calling me now.
I usually first hear "Is this (your name here)?" and answer, "Who is calling?" Sometimes I don't get an answer, just get the question repeated. I find that aggressively rude and hang up. I like the idea of just answering and saying nothing, though. I suppose I'll try that, because every so often it could actually be a legit call. And I know lots of older people, and some of them absolutely cannot get their minds around the idea that someone wouldn't rush to answer every call at panic speed and surely talk to whoever called, with great respect, and for any reason. That's what they do, after all. If they miss getting a call through to me, they think it's a big deal and want to have a discussion about it.
