First of all a 121 Area Code is not legit. Let the answering machine pick it up and of course no message. Besides blocking numbers which really does no good because all or most of them have hundreds of numbers they call from. One of the best things I do ( if I am home) as soon as I see unknown #'s is to switch my fax machine on. This slows them down for a while. I think the federal government needs to step in and put it on the telephone companies for sellin phones to these illegal people.
Said they were from American Brace. First thing said...."Can you hear me okay?". My response...."No, I cannot hear a word you're saying.". Never, ever say yes to that or anytime they ask you a question that would obviously be yes. They hung up, lol.
Received a call to our land line from this number today (29 Apr 2017) at 5:44 pm (Central Time). Caller ID: Invalid Number. Not answering that! No message left. No doubt some scam call.
