This can be called a foul. But remember, when the offense set a successful screen. The person with the ball is now past his defender and may have an open shot or even a layup. If you call a foul and stop the offense from completing a play they performed successfully (and the defense did not), you are rewarding the defense.

So, for me to call the foul, based on your description with hard contact running into the screener, the offense play must not be about to attempt the scope. Otherwise, I go up with the foul.

That game management.
