Joe,
Back when I was working and had to work 30 and 40 hours straight at times, we had a guy that would call the motel any time I got a chance to sleep and ask me some question. I asked him to stop doing it and he wouldn't so one morning around 2:30 I called him and asked him if he was awake. He said ,"Yes now what do yo want?" I told him nothing I just wanted to wake him up. He never bothered me after that.
