this number calls everyday and is a nuisance caller

Been getting calls, finally answered & they said bye & they hung up.

Get calls from 770/196/4852 all the time. No one answers when I pickup. Don't know what low life it is but I am getting tired of it. Why can't someone enforce the do not call list or is it just a waste of time signing up for it? I get two to four calls a day from telemarketers and can't seem to stop them

We're on the No Call list too, but that doesn't seem to stop some people. However, we love caller ID--if we don't recognize the name or number, or if the readout says "unavailable" or "private name", we just let it ring. No charge for the ringing, and they wasted a call (whoever "they" are : ) If somebody wants to talk to us bad enough, they'll leave a message and we'll decide whether we want to call them back!

I'm not even able to block it, as when I go to add it to my blocked list, the program says that it is an invalid number.  These robocallers are a nuisance and being on the DNC list doesn't stop them, as they hide behind spoofed numbers that can't be blocked or are numbers that are not in service and cannot be properly reported and dealt with under Federal law.
