Call SMS filter Lumia 1020 won't block text

[shielahswshielah]

It's good for blocking calls, but it does NOT block incoming text, it will show its blocked but it still shows the text msg in the blocked text so they still come thru and can still read them it just does not put it in your text thread, I want it to block all together, I don't want to be able to read it in my blocked text, it won't keep it from still coming into my phone, it needs to be updated/fixed so it actually does block the text from coming into my phone at all, Lumia 1020 & 920
Is there a fix for this???
I don't want yo be able to read a blocked text
