Hi
Did you get an automated response? We got one saying they had noted our flight was July 4th (I sent it 2 weeks before on June 20th).
Then I waited for a callback which we didn’t get until Friday July 1st. We then paid for upgrade and picked passport up that afternoon at nearest passport office. Flying this evening.
But I would phone them if you didn’t get automated response to tell them this. When you call, press option 8, then option 3 because this is very quick to answer- usually within 10 minutes.
Good luck 🤞
