Who called from 5713923718

I didn't bother to answer this same phone number, and they didn't bother to leave a message.

Same here.

6/7/12: received call, let it roll to message machine, left no message.

6/8/12: received call, answered it, dead air and I hung up.

I'm on a no call list and these jerks still call.  No idea who/what is calling or why.

Lengthy recorded message assuring me that I could reduce my electric bill by 30 to 50 percent simply by taking part in a survey.  Caller ID read only "Reston, VA".

Whoever they are, they call every day.  They leave no msg.  If you call them back you get a recording saying the number is not a working number.  Same old nonsense, as if anyone would give a company money over the phone.
