Would not disclose who they are until I gave my identity - but they had called me. Asked to be put on their "Do Not Call" list - she said they didn't have one. Yet the initial message indicated that they did. I called back and took that option. We'll have to see....
Got called from 657-202-6723 - woman said it was a magazine subscription service - told her I wasn't interested, that this is an unlisted number, and please remove it from their list. She apologized and hung up.
