It is a sorry state of affairs when you pay a phone bill and the company is in cahoots with advertisers or anyone else who they let disturb you without the ability to block them. Especially since the "Do Not Call" registry doesn't seem active or something.
I was a 30-year (!) member of the World Wildlife Fund until I started getting these calls (to contribute more than I had given in the past) two years ago for the first time. The following year I refused to renew my membership and replied to several postage-paid membership renewal solicitation mailings with an explanation of why I quit: namely, these insulting, highly unwanted telephone solicitations. Yet, now these imbeciles are calling me again. They clearly have no regard for their members; they just want the money. Maybe they were legit in the past, but now they are first and foremost a money-raising operation on a par with all the other telephone scammers
