Add your phone number to the national "Do not Call" register. Give it a couple of weeks and fewer calls will start coming in. When they do, tell them you are on do not call list and will report them if the activity continues.
<blockquote>"On my cell I rarely answer a # I don't recognize. I then come to this site and check the number. If it is listed like this one, I add the number to a contact name, zscam1 or zscam2 etc and flag to automatically reject the call."</blockquote>
WRT adding unknown callers who do not leave a message, I do the same.
One difference being, over a period of several years I now have ≈100 numbers in the reject call list.
Answered phone, silence on the other end. If I get a charge I will be furious! My phone is registered with state and federal Do Not Call list. I have no clue who this is. UGH!
