---> Connie wondered, "Any ideas who this might be?" <---
I have an idea, but it might be a little far-fetched. It's either the Tooth Fairy or the Bat Phone.
Really, people, stop asking other people to do free work for you. We already KNOW you come here looking for information, so don't just say you are here looking for information! Either look up the number yourself, and if there's no information available here or elsewhere, at least give us some clue beyond the Caller ID and Caller Name themselves that might help us track them down!
Otherwise, you are just contributing to the noise.
