So tonight when we got home the voice mail thing was flashing, again, on the phone. This time it wasn't a political call, but a mysterious call from what appears to be a student loan collection agency for a former (like 20 years ago) coworker. It's supposedly urgent that we call back. The individual for whom they're calling used to be a friend, but we had a fairly major falling out in 2005 and he moved out of state soon after. My question (since I don't have a history of delinquent debts and thus no experience with loan collectors): Is it common for collection agencies to dig deep enough so they try to reach individuals through past acquaintances, or does this contact mean this guy actually supplied our home phone number to someone as a way to get hold of him? I'm not thrilled about either option, but if it proves to be the latter, then this guy might want to count his blessings that he's out of state, because if I could reach him I'd give him a piece of my mind. I mean, what the hell?
