Some sort of pitch for Energy efficient home improvements that may qualify for a credit, etc.

another hang up

Yep, just called and the last 4 digits match my business partner's cell, so I picked up. Nothing.

Spam caller.

I received a call at 8:33 this morning. I am not happy.  This is an energy conservation company. I called back. A recording came on. Press prompt 3 to be removed from their list. I will see if this works. I have them on call block anyway.
