I also just had the same problem.
A big company but has a very slow and untransparent way of working.
We all have to spend money to rent a developer account to upload our apps to the store, spend a lot of money on infrastructure. I even had to hire RevenueCat service to process in-app purchase.
Their slow handling makes me miserable. I don't even know if they will keep quiet or find some silly excuse to rob me of my money.
If they continue to remain silent, is there any way I can sue them?
