I've been getting calls from these people every day for months now, sometimes several a day. I finally answered and it was a spiel about a new kind of business loan...the guy was very pushy and insistent but I told him that I operate on a pay as you go basis and was not interested...to put me on their "do not call list", which he repeated and the line went dead.
Sure, sure & the black helicopters are on the way. Nope - it's a scam. The idea is to get you to enter code on your phone to JOIN a conference call. Except you are turning over control of you phone to someone else. They will enjoy free long distance until something gets done about it. That's usually when you get your bill.
