Keeps calling at least 2x per day.  No answer when picking up.

I'm 90 yrs old this # keeps calling me but never leaves a msg. I'd like them to knock it off.

They called 12 times today. No one says anything when I answer.

Called 9 times today.  I finally blocked them.  So annoying

Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.
