I just received a call from this number with a recording from a credit card company? I didn't think to listen to the name of the company and notate it and I wish I had. They said something like they were calling about our credit card account, there were no problems and they were just letting us know how to lower our interest rate. Then they said to speak to someone live, press 9.
I pressed 9 and got a guy who said, "Are you responding to lower your interest rates today?" and I said I responded to say that we are on the Do Not Call list. He said nothing further and hung up on me.
