I get a call from this number on my cell phone 2-4 times a day.  They never leave a message.  One time I did answer, but no one replied.  Is it a telemarketer?  How can I have this stopped?

i don't pick up because i know who has the number 213-232-2370 keeps calling.  no message has been left, but i've received at least two calls a day since june 26.  haven't called on weekends yet.

I got a call from this number too.  Who is it?

I've been receing these calls for the past week at various times during the day, but no message also. I finally answered and got someone to reply, This is a telemarketing firm in Los Angeles. It from from my local newspaper and I intend to contact them also.

After posting on this site Aug. 31, the calls stopped coming until this week.  Now they are coming 1-2 times a day again.  Any ideas on how to stop them?
