Who called from 2182970346

I called the number back and a message said they're solicitating money in my neighborhood. but wouldn't say who or what it's for.

7/27/12  7:45pm  Unknown on caller ID.  Seriously, why do you hide behind unknown if you really want to trick and scam people in their homes?  No message was left - isn't that a shock?

Have received multiple calls from this number. They don't leave a message.

I have received numerous calls from this number over the past week but when I answer, I only get "dead air".

Just got another call from this number. I didn't answer it.  I have had several others from Brainerd, MN.  Don't care for this nuisance.
