Blocking "Restricted" Calls on Smartphone

I've had no problem blocking calls on my Samsung Android phone (Verizon), but when I receive a call that reads "Restricted" on the screen, it can't be blocked. The call is undoubtedly a scammer, and it's a sly attempt to prevent blockage since no number is displayed. These people are a pain. :M

This statement is not correct. I have received Restricted Calls and all as I remember were from Law Enforcement. That said I assume a scammer might be able to use that but in my experience the scam calls use a phone number close to mine.
