These people don't give it up, they're relentless! I've told them several times that I'm not interested in getting newspapers. That doesn't stop them. They call asking the same questions about the newspaper.
My advice is to get a call block app on your smartphone and dial *67 on your landline. Otherwise they'll keep calling non stop!
They've been calling every few hours, every damned day, which I would call harassment. I'm already a Post Gazette subscriber, and I don't know how to make them go away. I screen and don't pick up when I see the number in my caller ID.
The calls are not coming from 800 Notes. This is a place to report them, but it is up to you to decide to take action, check posts by Tamianth, BigA and others how to do it. Also, look into call blocking.
