Is the admissions officer for the sixth form never responding to messages?

This year I applied to sixth form, I emailed many admissions offices and even visited two schools in person. Two admissions officers asked me to email them my grades. Then I went to the school's reception desk and was told to come back if I hadn't received a reply by September 15th. Now it's November and I still haven't heard back. Do admissions offices always ignore messages? Or were you already rejected when they asked you to email them?
