If you have an iPhone you can BLOCK the number easily. If not contact your carrier to see about blocking a number. I don't know about other cell phones.
What? Are you kidding me? Scammers don't care if you are on the do not call list. That's laughable. just block them. That do not call list is a freaking joke anyway.
This person called yesterday, barely able to speak English and asked me "are you behind on THE mortgage". Excuse me? I told him no and don't call back, I'm on the do not call list. They called again today. thank God for auto reject calls on Android.
