Who called from 7083822173

They keep calling & my Caller ID shows UNKNOWN for this phone number, so they must be blocking their name from appearing. I don't answer calls from people I don't know, and when the answering machine picks up, they hang up without leaving a message.

call the number back, listen to the message and press 3 to be removed from the list.

I agree it was a spam call.

I just received a call from this number again.  I didn't answer it of course, but it is annoying.  Who should I report this to?

That number calls me everyday now for about 2 weeks,  It's a recording that says they are with the WCA.
Don't know and don't care who they are-I hang up.  I work nights and would like to strangle them when they wake me during the day..Caller ID simply says Oak Forest,IL
