Caller ID showed number but no Name (out of area). I just don't answer these calls. Left no message.
Good info here. They usually don't call back but I block after 2ed or 3ed call.
The Caller ID read, STAN LEE, the famous cartoonist. So I answered, and said, "If I'm not speaking to Stan Lee, I'm hanging up." The caller replied, I'm calling from Microsoft Technical Support. I asked to remove my number from their list and hung up.
