Waste of good piano wire. Everytime you get a phone call from someone looking for a donation or any other call that's intended to scam money from you, send the phone company a bill. You don't pay for anyone to use your phone service for solicitation or advertising, you pay your phone bill so you and those whom you choose can use this service....
I suppose you could just deduct it from your phone bill....then when the inevitable crunch comes...take your phone company to court for misrepresentation.
