They ask me level pro too (source of wealth) and provided it a lot of time (all docs required) but everytime was declined in few minutes (usually binance take not less than 10 days for verification!)
I don't know that well all Binance requirements. But since you've already sent all the info to Binance, maybe you could ask guidance on what they didn't like/what you can send different. (This way you may also get to discuss with a different support operative since the first one was not helpful).
Again, it's just an idea. I'm really sorry that you got caught in this crazy situation.
Clearly the SEPA part will get fixed at some point and then the communication channel with the bank should get back to normal; but I don't know who can give a proper time estimation for that...
