Same thing. I have been receiving calls for about 2 years. At first they would identify themselves as "Credit Card Services". I have complained about a dozen times with the DO NOT CALL service, but no change. They just change the number they use and call me again. Really irritating. (I watched my language)
Got a hang up. And yes, I get multiple calls from this "credit card" agency. But I am frustrated. I reports these to the govt and fill out the forms and they seem to do nothing to shut these scams down. That would be great use of my taxes! Shut these creeps down.
