I had a very similar experience with Wise recently. I finally managed to find a document they deemed acceptable (at the fifth attempt) the day before the deadline. At no point did I receive a clear explanation as to why a document was rejected.
After the second rejection I hastily transferred all of my business funds to other accounts, and have no intention of returning.
