My wife's cell-phone (which is unpublished) was recently used by an agency purportedly offering "rebates" for HVAC upgrades. My wife met with the representative about 30 minutes ago, and, as we suspected, it was a gimmick. When my wife asked how the company got her cell, the rep replied "from PG&E". Bottom line, privacy policies, such as they exist, are leakier than ever. When a public utility starts selling your information and cell number to the world at large, it's "caveat emptor" out there.
