I have to agree that the author is somewhat responsible here. Reading it I don't get a strong sense of urgency or ownership.

If this work was important, then why wait on another team who give you a "no telling when" reponse? Get the team together, and assign someone to do it same week. Don't do half-assed follow ups then complain when the dashboard team (which has already shown you it's not their priority) doesn't do anything about it.

If it isn't important, then go focus on the important stuff.
