Sorry man, that ship has most definitely sailed. I was put on the waiting list for braces 2 months before I was 17, and I got them on 1 month before I was 18. The problem was I was referred when I just turned 16 so almost a total of 2 years I was waiting to actually get my braces on. Even now (I've had them on since last June), I still haven't had my bottom brace put on, I think I'll get them on the 27th of this month. But long story short, no I'd say it's borderline impossible to notify them in 2 weeks.
