We've had our home number for about the same length of time, since the early to mid 1990s. More than once we've people call daily, sometimes several times a day, asking for someone we've never heard of. They won't ever identify who they are, but I was eventually able to determine that they're "zombie debt" collectors. It takes serious effort to find and squash those insects. In each case I've found that they were bottom-feeding law firms, which is convenient. Clear, strongly worded, hard copy letters sent by registered mail with CC to their state's AG, the state bar association, one to the CFPB, and one to the FTC thrown in just for good measure made the calls stop. Then a year or two later they start again, different players, same game. Now we have Ooma send all unknown calls to voicemail. They almost never leave messages, and when they do the messages are easily deleted.
Had something similar happen. And when you consider my name, it was an incredible coincidence....
