I have been getting calls from this number. How do we block it??

I received a call today, and the rude insistant man on the line said he was raising funds for Lukemia research.  After listening to his speal, and telling him I don't give information on the phone, but said if he mailed it to me I'd look, he tried to tell me I he wasn't getting through to me.Anyway, with his attitude, and the google history of this number, I believe that it is a scam number being used.  I would advise not to give money to this phone number.

Got 17 calls from this number - called it back and it's the Children's Leukemian Foundation.

As a mother who of a child with leukemia, I was very disgusted to hear that one of my co-workers received a call from this number, and was very rude to her.  He phoned last year, and rudely insisted that perhaps her donation would be enough to find a cure, after she repeatedly told him that she donates to other charities, and is not interested.  He made her feel very guilty for not donating.  Plus, you should NEVER donate over the phone.  He phoned again a few days ago, and again was very rude.  I've been dealing with my daughter's illness for 2 years now, and have never heard of this foundation in Alberta.  I do see that there is a foundation of that sort in Ontario, but I have no idea how legit that is either from the information that I've read on their website.  They don't give you a contact number, only a number to call to donate.  Their donation form only has an address, no phone number.  Whatever you do NO DO DONATE ANYTHING over the phone.

been getting calls from telemarketers, this guy being the main offender.

I got a call this morning -- once I answered the person said one, unintelligible, word and then hung up.
