Who called from 8106256831

Called once, no message left. Name comes up as Brittani Mance on my YouMail.

I was called twice, one week apart. Did not hear a response to my "hello."

Got a call from this one today. No message.

This number keeps calling over & over,  no one is there when I answer..  Why do they do that?

Calling it covering their tracks. Most won't use working numbers to avoid being caught, or to appear halfway local to give them a better chance of getting an answer. Study up on call spoofing and you should be able to see. Don't return calls to mystery numbers, either.
