Initially they were calling for my husband who passed away almost 9 years ago. I've no idea what they want and didn't want to get into it with them so didn't return their call. I screen all calls routinely, especially from toll free numbers and when theirs comes up I don't answer. However, a few times I was really annoyed and picked up the phone and they hung up. Now there are continuing calls with no messages left. I would like to block their number on my landline. How do I do that?
