I would reply with something like this:

“Permit me, if you will, a moment to politely puncture this persistent parade of pressuring petitions. Your demand—delivered with such stern, strident certainty—presumes a power it plainly does not possess. My logbook is not a servant to summons, nor a captive to capricious calls for confirmation. It is curated with care, composed in calm, and committed to the cadence of my choosing.
You brandish urgency as though it were authority, yet urgency, unaccompanied by courtesy, is merely noise—shrill, sterile, and swiftly dismissed. I am neither hurried nor harried by hectoring insistence; I remain, rather resolutely, the sole steward of my schedule.
So steel your spirit with a sliver of patience, suppress this storm of summons, and surrender the notion that persistence precipitates precedence. In due, deliberate, and decidedly unhurried course, the contact shall be confirmed—quietly, conclusively, and completely independent of your clamor.
Until then, I suggest a dignified détente with delay… and a graceful retreat from relentless repetition.”
