just called, auto-dialer, picked up by caller and loud boiler room in background, claims to be "working with customers on saving up to 75% on energy costs". No you're not I told her as I flung the phone down. Instablocked via my Ooma blacklisting capability.
They called me at least once a month offering something about solar panels or energy savings... I asked to Do Not Call me anymore and they still doing... so I added to my reject call list
