I received a recorded message (female voice) saying that this was a call regarding my credit card, but that nothing is wrong, only that I may qualify for lower interest rates. She said to stay on the line to speak to a representative. A guy answered and when I asked him which one of my cards he was calling from he said they handle Discover, Visa, MC and I said I want to know which one you own. He said something stupid like I have to sign to have them own my card! I said I understand how that works but I am asking you which credit card company are you with. He hung up. I'm putting this on my facebook too. And I'm reporting them because I too am on the Do Not Call registry.
