My caller ID says the call is from "LOWELL MA".  I do not recognize the number, so I refuse to answer the phone.  They called 4 days in a row and never left a message.

This number has called me twice this week without leaving a message. If you call back private an automatic recording comes up saying this number has been disconnected.  Sounds like a scam to me.

Answered twice, no one there.

I have been receiving calls day after day, sometimes multiple times a day, and they never leave a message. More than likely a scammer.

This number call me every time never leave message and when I pick up no he dosen't talk .
