I'm getting calls from this number as well. Time to add it to my spammer address list. I have 9 "Spams' in my contacts list. Each one is filled with these numbers. I set the ringer to silent and don't worry any more.
I have an app, I think it's called "who's calling" it let's u "ditch" an incoming call so each number that calls, hit the ditch button and no more calls from that number. And by the way, the app is free!
I'm on the do not call list keep getting calls first 609-145-8854,702-520-2413 now 302-789-0270 do not left message they are driving me crazy, But I do not anwer and they do not leave any message.
