i picked up on the first ring and covered the mouthpiece with my hand. A live voice said hello, i said nothing. Voice repeated hello? i said nothing. Voice began spiel about "are you paying more than seventy dollars for your electricity?" I said nothing. Voice said Hello, can you hear me? I said nothing. Caller hung up. Nice female voice, i was tempted to start breathing low and heavy, but i didn't. Caller never said her company name or anything, but it seems it was a call to get one to switch energy providers. I read somewhere that once they get you to say "yes", to any question, they can alter the context of the call as "proof" that THEY were called, so they can avoid charges if someone is on the do-not-call list, which i am.
