It's good to see that you've made an effort at contacting the school. Perhaps that particular email address is not in use. You should try another or visit the place yourself. Well, you see, there's no way of documenting or presenting forth verbal conversations that took place around ten years ago. Like I said before, I'm not the one with the problem and nor do I need to see evidence. This is your query. And I wouldn't just go by hearsay or assumptions or as you put it 'social-media and internet forums.' Why don't you begin with asking the scholars if you haven't been able to get through to the school as of yet? There's a lot more I could say but I really do not wish to go any further with this argument, purely for the sake of Allah and He is my witness. I feel that if you are sincere, then you will have husn al-dhan upon this school, until such time you receive a reply or an answer.
