Get lots of calls from this number every day. I don't answer because there is no caller ID and I don't know who the number is. They never leave a message on the answering machine. Does anyone know who they are?
Just call block... not sure if the same method is use to do call block, but go to RECENT CALLS > long press on the number>> an option should put up >>> Option; CALL BLOCK or REJECT CALL.
Hope that helps...
