Who's going to do that? It won't be anyone on here since you can do that better than we can. This site doesn't offer call blocking, or placing individual's numbers on any no call lists.
Even if this was a legit charity, never, ever give, money or information over the telephone. If you feel the need to give, go directly to the research hospital and give. St Jude in Tenn is a good place to start for children's cancer.
I got a call from them today, saw it on the CallerID. I sort of wished I was there to answer it. The conversation would have gone like this 'Oh, you want a donation for children with cancer? Well my 5 year old has an inoperable brain tumor and has been in chemo for 2 1/2 years. Can you make a donation to me?" - I think they would have hung up at that point. (It is a true story, she has an optic glioma).
