Sounds like: "I have a specific protocol for interacting with me, and you did not follow my protocol."

Some possible responses to that:

- "How was I supposed to know this the only way to get your attention? It's your fault for not publishing your protocol."

- "I have tried to get your attention in exactly the ways you prescribed, and it's your fault for not responding to any of them."

- "Your protocol is unreasonable and I have escalated to management to discuss better means of interaction."

- "Oops sorry, let me try that next time."
