You can call the number (202-558-4517 -- at least it's a legitimate number, apparently), there will be a fairly brief recording about the organization, then it asks you to enter your phone number if you want to have it removed from their call list. If you do that, then there is a message stating that by federal law they have 30 days to remove the number, but they will try to remove it within a couple of days. I can't verify this works because it has only been a few minutes since I submitted my number to be removed. Actually, had I listened to their message on the original call, I doubt that I would have disagreed with it all that much; just don't like the way they deliver it.
I keep getting calls from several 202 numbers, some labeled Ken Hoagland, some
just Washington DC. I have reported them all to the Do Not Call List and blocked them.
Never any messages left, and I don't pick up
