I've been getting calls from them - my caller id simply says Memphis TN when they call. After reading Danny J's post, I called the number back and got a recorded message. Like he said, after the message there is a pause and then it goes on to give you the 'remove from list' option.
They make you jump through some hoops though: "Press 1 to remove your number from the list!" *presses 1* ~recording plays telling you they are a children cancer charity in the hopes of making you feel guilty and change your mind. Recording then says if you are sure, press 3~ *presses 3* ~recording then requests you enter the 10 digit number you want removed~ *enters number* ~recording repeats number back to you and then says you are removed but it can take 30 days for the request to go through - they'll do their best though. It then says 'good-bye'.~ I waited a fair amount of time after that but there was nothing more. We'll have to wait and see if it worked.
Yes, from St. Jude's. I gave to them over a year ago through the mail only - started receiving the phone calls insistently since. I will no longer give to this organization with these kinds of tactics that they use which is unfortunate because they seem to be a fine organization overall but really disappointed in how they badger people into donating!
