I received a dozen calls in last two weeks, no message left, when I called bac in the evening, the answering machine would say "thank for calling, our workign hours are...". I called them back this morning and they told me that they are a joint effort between them and state of California about energy conservation, and that they are calling homeowners. I asked not to call me again, and they said they will put me on the no-call list.
