We get at least 20 calls per day that show up on the caller ID without a name and with either no phone number or a number with a New York metro area code. We usually don't bother answering such calls anymore. ("If it's important, they'll leave a message.") When we do answer, there's often no one on the other end. Other times, it's a tzedaka organization we may or may not have heard of.
Is this experience typical? How do you deal with it? Is there any way to get the number of such calls to decrease?
One organization calls repeatedly and insists that I pledged to give a donation. I'm sure that I never did, but they may have misconstrued one of my responses during one of their "can we send you an envelope for your pledge of $N" pitches. How can we get them to remove us from their books?
