Hello, i am in the exact same boat as you, apart from i travel on the 12th august. my application has been stuck on “received” since 14/06/2022. I email upgrade team a week ago. not heard anything, have constantly emailed different departments and called different departments with no luck and everyone saying the same thing.
interesting you mentioned about the 8th august, they never said anything like that to me. My documents are in Durham apparently, however i might go to liverpool tomorrow to see if i have any luck showing up to a passport office. running out of ideas. We just need an answer and i find it crazy out of all the departments, no one can provide one!
very stressed. hope you get it sorted 🙂
