Whenever that happens - either knocking on the door, calling the room or just entering the room - despite DND sign displayed the night is automatically for free following my complaint.
If the guest is woken up then the point of staying at a hotel is forfeited so I request the nights charge to be waived. Maybe that helps the management keeping their housekeeping policies in check.
