How can I stop iCloud from syncing my data without permission?

I have never used and always turned off iCloud AND any app that shows up under iCloud settings is always turned off immediately after getting installing the app, but this does not stop iCloud from attempting to upload my data to apple servers.

I currently have to go back in to iCloud settings every couple weeks, to turn off apps that magically get turned on (today it was Messages, Phone & FaceTime, and Music that had magically turned them selves on for sync).

I have not added any new apps, made changes to any settings, or upgraded any app or the IOS (all these are set to manual). I also have a new message in my settings that states "Some iCloud Data Isn't Syncing", which should not appear because iCloud is turned off!

How do I stop the apps from getting toggled on for sync, turn iCloud off completely (it says off but there is something still working), and or preferably remove it ?
