Call went into voice mail but did not leave a message. Caller ID: "WOMAN2WOMAN"

Got 2 calls today, several in past few days.  No message left - doesnt even wait for voicemail.

Called yesterday morning and this morning at about the same time
Caller ID shows Woman2Woman.
Nothing left on answering machine
Read others have received similar call from same caller ID

Annoying Calls...... Never leaves message.......

have been receiving these calls for days no voice message ever left. this is a tip  Call the nember back and just let eventually someone will answer then tell them to remove you from their calling list. we'll see if it works

Called but left no msg. I'm on national do not call list yet I still get 3 out 5 calls from these types. It's a crying shame in this country when you can no longer have a home phone without being harassed.
There are women living here!

I did some research and apparently this company also calls people on from another number (847-905-6756) and allegedly this is their website http://w2wbcf.org/. From what I can find they are a breast cancer foundation, but most of the info I've found says they are a scam and keep most of the money, if not all. I have no proof of that, what I do have proof of is they continue to call repeatedly and when I answer I get a hangup. This mornings call and hang up pushed me to file a complaint with the FCC, you should to.
