Student finance Help!!

Hi, I have a very toixc and strained relationship with my mother, and I needed her details for my student finance account as I have only been living independently for two years. However she lied to me and told me she completed those accounts only to find out she hasn't my my finance application hasn't been processed.

I'm screwed for university as my first rent payment must be payed by 27th September and my application will not be in by then.

Does anyone have any help or advice that I can use, I'm absolutely devastated and panicking now as I start university in just over a month now.
