Caller ID simply says "None"...............good way to have call blocked

Called this am and asked for me by name.  I toyed with them and said the person they asked for was my grandson.
Said it again and then dead air.  I hung up.  [***] scammer.  Called ID just says Amite, LA.

Stupid recorded calls! I am really thinking of getting rid of my home phone, the do nat call list is a joke!

Spam call

Scam calls...several times a day. When the call is answered, to only dead silence on the other end, so, I think it is possible that information is being pulled off my smart phone. So, now I either don't answer or blow a whistle, as loud as possible.
