Nuisance calls

I've had the same issue. With the land line, it's only an occasional thing, and if I don't recognize who it is, I don't answer. If it's legit they will leave a message.

For the cell, I activated a setting called "do not disturb". It will only ring for people in my contact list. All others go to voicemail and the scammers just hang up. It's irritating as hell, I was getting 30-40 calls a day before I change the settings.
