What should I do about these harassing robo-calls?

I’m getting calls several times a day from the same number. Usually I look at the caller ID and don’t pick up but it still means I have gotten up. Once I picked up to see what it was and it’s a Medicare scam. I’ve yelled at it once or twice and today “Pressed 1” to yell at a person but there was no one there.

Should I go through the hassle of calling Verizon and reporting them or will they give up eventually? This is a landline so I can’t block.
