Student finance- applied for the wrong year

Okay so… I applied for the 2025/26 academic year, but I don’t start until 2026/27. I’ve tried to cancel my application so I can start again, but it won’t let me. It just keeps sending me back to my account page. I’ve called the number and tried every option I can to talk to a person so I can get help, but it keeps giving me an automated response saying I can do all of it online (when it won’t let me). I’ve tried the chatbot where it directed me to an officer, and none of his responses worked.

How will this (quite admittedly silly) mistake affect my student finance? How can I actually cancel it? What do I do from here? Kinda freaking out to be honest.
