"i'm still waiting for my braces its been 6 years..."

i was referred to the dental hospital for a check up i think, June 22nd 2012 i had the check up they said i needed some sort of surgery i guess there was no communication what so ever between staff and patients, i hate that, so they said that i'm still growing and they will be in contact within 15 months time and now its been 19 months and they still haven't been in contact i try and call them but it always tell me to leave a message and they never call back i'm sick and tried of this it's been to long and every dentist i've been to say the same thing . I'm afraid that by the time they call i'll be 18/19 and i will have to pay for surgery and i don't want that. I just want my braces!
