Some charity something about Cancer Support supposedly located in Dearborn Michigan. The message was a crazy mixture of robocalls and personal conversation. The whole call seems fishy.
It's called Cancer Support Services. Most of its expenses are fundraising. Apparently it is used to raise funds for another charity so the second charity will look like it is spending very little of its own assets in fund raising. It's not a scam, I don't think, but kind of dodgy. Read this article. Don't give them any money and don't make any pledges over the phone or give them any credit card information.
