Stressing and upset

So, I applied to a school for sixth form and it's private but I received an email saying I was too late. I emailed a woman the day before the closing date and she said the latest I can submit it was the 31st even though it was 26th. I sent it on the 31st and now the whole "process" is over. No test no interview just paid the money to be told no. It's not like I'm not a high-achiever (not in a cocky way) but I'm an 8 or 9 in all subjects and predicted an 8 or 9 in all subjects (a 7 in one). What do I do ,because the exam is on the 9th and I need a bursary and they say they have had a high volume of applications? Do I call them today (mon 5th)? Is it enough time? I'm just really upset because I've invested so much time into this school and research and whatever and it's honestly my dream.
