Called - answered it.  No one on the line.

Called my house several times over the past couple weeks.  Every time I answer, no one was on the other end.  Called again just now and a man identified as himself as calling from xoom energy regarding switching our electricity supplier.  Asked to be put on their do not call (which I should be already.)  We'll see if it works.

SCAM

No answer. Told them to pizz off
