Just got a call from this number. I didn't answer. Whether is about my auto warranty, credit cards, or some other random scam, if you don't ever pick up they'll eventually stop calling. Or just tell them you don't have a credit card/ car/ whatever..
I just got a call from this number, pressed 1 and told the lady that I didn't know what service she was calling from and I'd like to learn how to be taken off this list. She hung up. I get a call from them once a day.
