We also pay off the credit card bill each month to avoid the interest but these scam places just keep calling. One about this time (noonish Central Time) yesterday and again today. And yes, we are on several Do Not Call lists.
Called back to remove my name from their list by pressing "1". Hope it works. I am on do-not-call list. By the way, it's pretty stupid to blame the President (Concerned Citizen) for getting unwanted calls. He didn't make the law and additionally, it's practically impossible to enforce as these companies just change their number frequently. Stop bringing politics into every subject.
