This number keeps calling then hanging up when I say "Hello" please get them to quit calling

I have received 10 calls from this number in the last 3days. I read that they are in violation of the federal telemarketer laws. So why am I getting calls from Oregon in direct violation?

This number is a number from an Oregon company called callerid4u. Paul Maduno is the CEO. His email is...paul@callerid4u.com and phone is..310-251-5420. Had it with these calls. I just sent Paul every piece of junk that has been building in my spam folder for 3 months. His number has also been give to fellow marketers. See how you like it Paul !!!!

I am sick of this, they call me all day and night no matter what time it is!   It's a recording with the name Debbie. The stress of this number showing up every night after working all day coming home seeing missed calls from Eugene, Oregon is sickening. I want this to stop every time I call back I get this damm music in my ear AND  no one EVER picks up! After awhile it disconnects! Somewhere, somehow it needs to stop. I am on the DNC list as well but that obviously that means nothing since they keep CALLING! Can I sue because I want to? Please tell me what to do.

Calls almost every week with no message, at around 7PM.  Never leaves a messag
