You rewrote the same message three times, and each version sounds sharper. Before sending it, put the phone down. Ask yourself what you need the other person to understand. Write that in one plain sentence: “When the plan changed, I needed you to tell me.” Remove the line you added only to hurt them. Read it once more. A careful message can still be firm. You are choosing words that explain the problem without creating another one.
