Picked up a call, without checking ID, from 'Unavailable'. A voice message said the call was in response to my calling about an advertisement on TV, and then I was transferred. A man asked if I was Carole, and then gave two different last names. I asked what TV ad this call was referring to, and he hung up! I dialed the number, and the only choice was to press '1' to be removed from their calling list. What a scam, and waste of time!!
