Need Help: SFE Mistake with Tuition Loan After Moving Unis and Repeating a Year

Hi everyone,
I’m in a really difficult situation and could use some advice or if anyone has had a similar experience.
I was originally at one university, but I failed my foundation year. After that, I transferred to a different university, where I repeated my second year. In September, Student Finance England (SFE) approved my tuition loan, and I started the year thinking everything was fine.
However, in June, SFE contacted me to say that because I transferred universities and repeated a year, I’m no longer eligible for a tuition loan. This came as a huge shock, especially since all the tuition payments for the year had already been made.
I spent over an hour on the phone with SFE, and they admitted that they made a mistake but said there’s nothing they can do about it now. The only option they suggested was to apply for a loan under "Compelling Personal Reasons" (CPR) because I was dealing with dyslexia and mental health challenges at the time.
Now, I’m stuck with a £9,250 tuition fee that I can’t afford, and it feels incredibly unfair to be in this situation due to their error.
Has anyone else experienced something like this? How do I go about getting the necessary proof for a CPR application? Any advice on handling this situation would be really appreciated, as I’m feeling quite lost right now.
Thanks so much in advance!
