5 calls within the first 4 hours, won't leave a message in person or on the machine. Telemarketer or scammer I bet.

I got a call from this number & when I picked up they wouldn't speak & then hung up.

they keep calling me - 4 times today - I picked up and waited 5 seconds and no one responded. I'm on a do not call list

number started calling today. no msg. I'm on do not call also.

Called daily this week, four times today so far.  No voice-mail message, call display only indicates phone number - appears sleazy (and I am registered on the do not call registry)

They keep call me everyday, and do not leave a message.
