Continually calling all hours of day and evening.  11/30/15 called after 9:00 PM

Sad but true.

Law enforcement can't go after all of them, but maybe they can select a few notorious ones and prosecute the crap out of them.

Made an attempt to return this call received recorded message from Verizon stating number was no longer in service or disconnected..... strange

Yes, CallBlocker works GREAT, and best of all ..... it's FREE ..... I downloaded for my Android couple of years ago.

I think I  have found a solution to these callers, I answer, press mute and wait for the hang up. I believe this works because the number of calls has diminished considerably. I think the calling computer thinks its a dead number and drops it from the list. Hope this helps others.
