They call our home EVERYDAY, about 4 times a day. I would just like to know who it is. When I answer there is no one at the other end. Why call? Aaaannoying! Someone please solve this mystery.

I received 4 calls in a day with this local number almost like clockwork every hour.  I have blocked it.  My caller ID states Chula Vista, CA  No one is on the other end. Since I have blocked it, they now have switched to a new number to annoy me.
