Caller ID shows "SAN MATEO CA." Heavily accented male said he was calling on behalf of "???? of America." I asked him to repeat and as best as I could tell, he said "Soda of America" (I'm sure that's not what he was trying to say). Googled the number and found this. http://spanbpo.com/services/lead-generation/
My wife answered-Green Energy. I think many scam companies use this number belonging to telemarketing firm. I blocked the number, but I'm sure other ones will be used.
