Need SMS blocker with certain options

[AC Question]

Hello, I'm looking for an SMS blocker which has an option to block text messages from all unknown numbers which aren't in your contact list AND also to delete the blocked messages immediately after receiving them so that you'll never know they were sent to you. Most SMS blockers seem to just move the blocked SMS to a separate folder so even blocked you'll still find out that you've got it. Is there a program that has both options at the same time? I have Samsung Galaxy S5 Neo. I would appreciate your help.

Which phone?
Which version of android?
Which carrier?

Which SMS app are you using?
Folders are not a common feature for SMS apps.

The normal behavior for blocked messages is to silently discard them when they arrive.

I have Samsung Galaxy S5 Neo as I mentioned above. My Android version is 6.0.1. As for my carrier it's not really popular since it's used just in my country. The SMS app that I'm using is Clean Inbox - SMS Blocker, but other applications seem to be similar regarding these two features.
