Called about a survey...I blocked the number as he was talking. My block history has told me he has tried to call back every hour for 3 hours since. Nothing phases these people. Slam the phone on them, curse them out, kindly tell them you are not interested. They are relentless. It's very tiresome. I can't imagine how these scammers or dopey companies think that by constantly calling and being hung up on and calling and calling again, you are gonna have some kind of Epiphany on the 60th time they call and listen to their spiel. Oh how I love the "Do not call" list, said someone...never.
