I asked the man the company's name. It is Credit Services. I filed a claim with the do not call registry - we'll see if anything comes of it (highly doubt it).
They called I answered to see if I could get off their list. The guy sounded excited to lower my credit card interest rate. When I told him I just wanted off the list he hung up. I called the number back, it said the mailbox was full. Another scammer, second one today.
