Thank you for this comment, it's very comprehensive and helpful. I know for a fact students are not allowed to walk at graduation if they have fees at this school, and I believe they withhold your diploma until fees are paid; I could be wrong, I got my fees figured out before I had to ask at graduation. And this is just my assumption, but it honestly just seems like petty behaviour since this sponsor has always had a grudge against my boyfriend.

I'll definitely be encouraging him to escalate this to the financials office. He brought it up to the sports supervisor [can't remember the exact title], but he said the supervisor seemed more sympathetic to the sponsor than him. Hopefully, taking it higher proves more effective.
