Always hang up on my Google Voice challenge. I block every number they use...

Bugging me, too.

They have the nerve to insist that they are not selling me anything even when I ask to be taken off their distribution list. They claim to be affiliated with PG&E and was calling about the California Solar Initiative.  All very official sounding names hiding a certain arrogance and denial that they are telemarketing at its worst.

They call constantly and I have not been able to figure out how to be removed from the list.
