It's like promising someone you'll come to their house on May 5th to help them move, then your kid gets the flu and you can't. Instead, you offer to pay for someone else to do the work instead.
The moving friend who doesn't want hired help because they won't do as good of a job then blames you because you broke your promise. He is especially mad when he finds out that if he doesn't accept your alternative, he's shelling out more of his own money to move.

Thank you so much, that explains everything.
