The caller I.D. for this number shows up as "309".  We have no clue who this is.  

This is that same old energy survey scam -- BEWARE!

Called at noon. Left no message.

Received a call from this number.  The female on the phone identified themselves as working for a company taking a survey on energy consumption.  Asked for average electric bill, any energy conservation updates like windows, etc.  Asked what type of home insulation, then offered a gift card to Lowes or Home Depot, then ended the call saying that someone would call in 1 hour to confirm her call.  Hope this helps

We have been getting 2 - 4 of these calls every day for the last week.  When picked up immediately, there is no one on the line.
They never leave a message.
