We got a call from this number today when my wife was already on the phone We have blocked this number, but our call blocker doesn't work with call waiting. She answered but hung up when she learned who it was.
The called us again today at 4:42 pm. The caller ID was CHILDRENS CANCE, and this time our call blocker blocked the call. When I called back I got the same recorded message that I had reached the Children's Cancer Recovery Foundation as I did when I called back 877-218-8360, which is also blocked. Apparently they use more than one number.
This number called me at 4PM and then again 10 minutes later. Any of these telemarketers get blocked if they call me a second time. "Children's cancer" appeared on my caller ID.
