An automated "caller" asks if I would like to speak to an operator to lower my current credit card's interest rate; to please press '9' now. It's a scam, because I do not own any credit cards. I pressed 9 and an operator picked up, asked me the question(as mentioned above), I told her no and the phone clicked/hung up. This scam has called me several times. I have Caller I.D. & tried to call the number, and I receive nothing except a busy signal. I am on the Do Not Call registry, and have a private number, yet this call still goes through.
