This number has called me every day for a week and 10 times today, alone. I would certainly call this harassment even if they did need to speak to me. No one has left a message so I have no idea who it is.

They say they are with some kind of Auto care....
the first 3 times they called I asked nicely..please do not call this number again
On Dec. 4th at 6:10 I told them Im going to report them..
my phone says its a call from California.
they have called me 35 times since 11/24/15

They call me as well from this number about ten times a day. I've never answered it but they never leave a vm. I call this harassment as well.

I got a call from this number this morning and did not answer because I did not recognize it.  And it only said California and I have never know 657 to be a California area code and I live in the state.  Waited to see if a message would be left..no message and I have deleted the number from my phone.  I figure if you really want to get a hold of someone and they don't answer when you call them, you leave a message for them to call you back.  I think this is some kinda scam.

This is getting to be a pain in the b!@#!! I work at home and these unwanted calls are a constant interruption.
