If someone books a room at your hostel and pays a deposit, then don't give away their room to someone else. Especially not without telling them until they get there. That is incredibly rude and it's the worst service I have ever seen. We came in the middle of the night and had nowhere else to go. We had to sleep in the car because of you. You ruined a whole day for us on our vacation that we had to spend on finding somewhere else to stay.
