Your data should still be in bsky.app's PDS, you just won't be able to log into their app. You could probably try to find or modify a bsky instance that doesn't accept blacklists from bsky.app, and then you'd be able to log in normally. As for why bsky.app is stalling you, it's largely because they don't have an internal process for handling data requests from banned accounts, or even a person in charge of it.
There may be a way to simply ask them to migrate your data to another PDS, but despite this, your account will still not be able to log into bsky.app. Unless you set up your own full bsky network or join another bsky network, you won't be able to get your messages to appear on bsky.app either, unless your friends have left bsky.app as well.
