A few weeks ago they called my cell while I was at work. I ignored it, and seconds after it stopped ringing, my office phone rings. I don't even know how they got my work number, but there they were calling me at work without permission literally immediately after they failed to reach me on my cell. It has indeed gotten out of hand.
Something in particular that rubs me the wrong way is that it's obvious they make no effort to look up your information before calling. On the rare occasion I do pick up, the response is usually mild surprise when I say I've already set up my giving for the year. Personally, I might be a little more receptive to whatever they have to say if I got the impression I was more than a name and a phone number on a list at that moment in time to my alma mater who's asking me for money.
