I'll second the suggestion above re: finding the actual person who has the ability to say yes or no. Face to face if possible. It's really easy for bureaucrats/bank officers/paper pushers to ignore an issue when it's an email or a voicemail. When it's a person standing in your office (being polite and logical but firm) it's usually much more productive.
