I can't speak for or suggest any app after attempting to installs several I've located. But what I can tell you is that when a call comes in, you can tab the three dots/lines and "report number as spam" options.. this will report the number as well as block them. But nothing is permanent so keep these files current and up to date.

Try:

Settings>Device>Blocking Mode.
Set time to always
Set Allowed contacts to All Contacts.
