"It starts at about 5 o'clock. It goes from about 5-9 p.m., there'll be 2, 3, 4, calls," says 93-year old Carl Arfa, from Boca Raton. He says sometimes they try sell something, sometimes it's no one.

"Until we have a worldwide system that can control all the cell phones and all the connections, we won't have a solution," David says.
"My wife always says thank you. She's very polite. I'm not polite. I was a sergeant in the army. I was never polite," Carl says.
