Supposedly can save electric rates please have your utility bill handy. Has called several times a day for last week. Finally pressed 5 to speak with person (very oriental heavy accent) I stated was on do not call registry and please remove me from this list. Asked to speak with supervisor and was refused. Stated would report them and they hung up. Same number called back within the same hour. What exactly is the Do Not Call registry for anyway? These people need to be prosecuted severely.
