Who called from 7813494717

WTH

Same thing as Jenifer.

Every time I answer they hang up.  When I don't answer, they leave no message.  (So, what's the point?)

Caller ID says "Norwood, MA" which is a town, not a company.  Time to contact Norwood Police to file a complaint, I think.

Good to know it isn't just me. I have the same problem.. They call several times a week, I answer and they say nothing. When I try doing a 'reverse lookup' I get nothing back.

no answer when I pick up.  Called back & received busy signal.  Very disruptive.

I see the number on my call screen, but don't pick up.
They hear the message to leave a message but don't.
