It's just a tel-marketer number. You can find a way to block it, but I'm not sure how. Try Google-ing your phone's model and functions to see if you can.

I get these calls occasionally on my personal cell-phone. And I'm only 16. How creepy...

I'm getting the same calls on my business number all day and no one answers when you call back. Same automated message... VERY ANNOYING!

I receive calls from this number at least four times a day.  They never leave a message.  When I call it back it says, please wait for the next available agent.  Does any one know about this number?
