Cannot create a business account for a new business

I do not think they will tell you why, I got the same twice and despite contesting and just asking for a reason twice they never answered

Long time Revolut user but just trying to create a business account for a new company and it’s asking for Proof of Nature of Business. I’ve submitted my contract with my client, told it about my business and it’s not enough. Since I’m a new business I don’t have sales invoices or bank statements.
Any help?
