don't they adhere to the do-not-call this?

Covenant House has called me mercilessly, leaving no message on my answering machine.  

Hi,
I called the 661-476-3025 number today and directly asked them to please take me off the list. I, too, have received many calls as well. The gentleman I spoke with apologized and kept me on the phone while he placed me on the do not call list. I was on the phone maybe two minutes or less. Hope this works, thought you might try this if you haven't already. I guess I will know if that worked real soon. Good luck.

call my home frequent times sometimes up to 4 * today never left a message on my answer  I have placed my name and number on the do not call.list and that was over 2 months ago and then they wonder why we hang up on them best advice I can give is as soon as you answer if you don't hear your name said right away hang up thank you hope this helps!!!PGZ

Please stop all calls.
