I'd like to be able to schedule a block on the mobile data and/or the wifi/mobile hotspot feature

[Utelias]

Any app that would enable me to do this?

Android 4.4.4; already tried some apps for this. Haven't found any that would enable me to block the things I'm looking for.

. Try Llama or Tasker

They allow me to block it so that the block cannot be undone before the set time?

Get Tasker

Tasker doesn't prevent me from turning the mobile data back on. I need to be able to block the change.
