If you don't want to be bothered from unknown numbers, don't answer them. If you don't answer, they will try a few more days then stop. The whole point behind caller i.d. is to know who is calling. Just because the phone rings doesn't mean you have to answer it.
Cardholder services is making spam calls from this number now. I am constantly getting calls from more and more diverse numbers. They also call from 609-227-4849, 813-444-5665 and 945-278-8365
