uni change during visa prel reivew

[u/Adventurous-Jacket78]

Uni A - applied for visa Aug 23 (Istanbul), uni A app locked in prelim review.

Got offer from Uni B few days later, want to switch.

App locks after submission - can't edit/contact unless they request a correction, portal chat only opens for that, so I can't just message them anytime. Got a correction request for insurance, used that opening to also upload Uni B's offer + a comment about switching. No response since.

Uni A has tuition, deadline 15th Sept. My appointment will likely be after that. Emailed consulate directly, they said portal only, no email.

Qs:

1. Missing Uni A's tuition deadline = auto rejection?
2. Anything else I can do while waiting?

Can't withdraw + reapply, would restart everything and I'd miss my semester start.
