Extra year funding confusion

I don't even know where to start with this as it's such a complete mess.

7 years ago had 3 years of tuition fees and 4 years of maintenance loans/grants. I actually had 4 years of tuition fees but one was disregarded due to compelling personal reasons. (I dropped out eventually as it was just the wrong time so I left after completing 240credits)

i was led to believe by student finance that I would be entitled to one more year of tuition fees this year as i hadn't had the full 4 years, my entitlement letter said I wasn't entitled but on the phone they said once the university confirm my eligibility for the top-up third year it would change

3 weeks ago my university finance office called them and she was told the same as me, that they needed to provide proof of eligibility on the course and then I would be fine.....fast forward to today and i call to ask for some clarification...only to be told I would never have been entitled as the year I paid my own fees and only had maintenance loans and grants counts as a year of finance...meaning I had had my 4 years. obviously I have already registered as I was told I was entitled ( however the adviser says no notes were made to show i had been told this and say that I would have been told I wouldn't be ( Like i would continue to chase if I already had been told).
I don't know what to do now, I can't continue the course as I don't actually have £9250 to spare and if I drop out I will still owe the fees.

I can't see any way out here??

Any advice appreciated
