Phone [Q] Need Help finding a good app

Hello guys..
Need help, its important.
I need a call/sms blocker app which successfully blocks calls/sms without any notification. Just like in the old samsung phones which had a blacklist and blocked call without notifying users that a call has been blocked. I tried the NQ call blocker app, It works good but leaves a notification about the blocked call in the log and fastlane.

Can u please help me with this either by stopping the notification or name me an app that does it without notification.
I use a Nokia X dual SIM.
