Who called from 6264072687

The caller ID says "EHE".  And they are persistent!  They called multiple times a day almost every day!

Called back and got a recording regarding energy efficient home products.

I've blocked these jerks - - they have harassed me for the past two days!

They called twice.  First time I did not answer.  The next day they called again.  This time I answered, but no one say anything at the other end.

this number has called the past two days....we don't answer the phone and they don't leave a message.
