Just received a call from this number.  Didn't leave a message.

Got a call on my cell from this #. Don't recognize the # but they didn't leave message. If you can't tell who you are I assume you are a telemarketer.

Answered, they requested by name me and identified themselves as "Breast Cancer" donations.

These people have called me three times over the past two weeks now. Each time they ask for "Grace" and when I tell them there is no one by that name at the number, they immediately say "Oh, well maybe you can help me..." before going into their normal read text asking for money.

This is a solicitation for donations for breast cancer "support" for an organization that is consistently rated as "bad" by those who rate non-profits. Very little of the money they collect goes to the cause for which they collect. Most of it goes to professional fundraisers and the "executives" that front the organization itself.

The "call" is pre-recorded dialogue being listened into by a live person (probably not an American native-English speaker) who selects the responses based on what you say.

So, if I ask, as I always do: "Is this a recording or a live person," they will respond that it is a "live person," which is I suppose technically true in that a live person is listening and selecting responses, but is not really engaging in a true dialogue.

I always ask them to repeat an unlikely word or phrase to test whether the person speaking is "real." In nearly every instance they end the call at that point. Then I block the number. I usually ask them to repeat "supercalifradgalistic."
