I don't believe this is any legitimate Obamacare call. I called the number back and got a non-working number announcement. The number is a fake; the call is a scam.
I asked what type of bank is this , Guy said to lower credit cards . Then I said oh so its a Telemarketer call , that is a violation of the Law . hung up on him .
Thanks to everyone for the information. I couldn't get to the phone in time to answer, and I was expecting a call. Because of this website I know that I didn't miss an important call.
