We get a call from them almost daily.  They talk about "my" electric company but it isn't the one for our area!  We are registered with the do not call registry and I report these guys to the do not call registry almost daily but it doesn't make any difference.  It is a recorded call and they are not supposed to call you even if you are not on the do not call registry!
