I have a policy. I tell them when they call me. I will call approxamitly 1/2 hour before coming over. If they don't answer, I will go onto the next job. I don't have too many problems.
Had a good one last week, Lady needed her refrigerator repaired. Called me in the morning, scheduled her for 1 to 3 somewhere. I call her at 1:30, no answer. Had another call close, call again at 2:15, no answer, so I go onto another call 20 minutes away. She calls back at 3:45 saying she's home now, I can come over. Told her i'm sorry, can't come over. She was pissed, yelled and hung up. Next morning, I get a call from her asking me if I could come over that day. I told her I was too busy. Yelled again, hung up. Haven't heard back from her yet, good riddance.
