Your vitriol will do no good because these scammers will simply move on to millions of other phone numbers and try the same thing. The people you should be mad at is the phone company who does nothing with your complaints because the outlaws pay their phone bills and that is all the phone companies want, just like the criminals who keep calling you. It's all about the money. You don't mean anything to either of them.

No message.  ID is just for WA...no business.  I refuse to answer...and I flag them.  So much for DNC lists!  Governmental joke on the public.  It doesn't work!  Surprised?

they hung up before leaving a message

didn't answer, no message, spoofed number, blocked them

AinComing  Call was the user id, that was a new one.
Blocked them like I have to do every single day now with a new number and fake calls coming to my unlisted phone number every single day for over 1 year now. I do not know what happened and how I got on these lists but I had to buy a phone system that would allow me block calls.
