Told the guy that if you do not call anymore, i will still contribute and he said fair enough and it takes about a week for the computer to make that happen. Funny before computers if you told someone not to call your phone number anymore, that was pretty much the end of it.
Called again Sunday morning. Looking for either a contribution or renewal. They have called four times in 3 days. May drop Nat Cons from my list of charities. They are the only ones so persistent.
I called back about 11:30PM - it was the Nature Conservancy - I requested they remove my name from their calling list. I am a supporter. They called about 8:10PM
