Called me tonight and I am sick of them. Please  see my comment  posted 2/8/2017  at the other phone number they use here in Seattle area 253-220-9602,

I did find a way to block them (at least on my cell), called "Should I Answer", a call blocker for Android that apparently checks against a database like the one on 800notes before blocking the calls.

Unfortunately the method for using Centurylink to block incoming calls is limited. Or was, our last experience with it was blocking all calls and asking "if you're an actual caller, press one". Then later, trying to enter the numbers manually and being limited to a certain number of numbers to block. They keep finding new tricks.:P

To date they'd only called our business. NOW they're calling us at home too. Blocked.

my numbers are on the national do not call list, but get calls anyway. when i answer nobody responds, i sometimes get a call 4-5 times a day from these people, a couple months ago they called me 3 x in 45 minutes. when  i see its them i ignore and let it go to voice mail

Scammers at best, low life robo callers that won't stop calling under the front of United Breast C!  I answered once months ago and told them to stop calling.  Must have been talking to a computer since it did no good.  I keep asking why can't the phone companies stop them?????
