What are my options?

Today I received my results for the end of my second year at BSc (Level 5). Despite failing one module (at L5) which I was aware of, I was confident that I’d passed this year and my studies would resume to my last year. However, to my surprise, I was told my studies were terminated due to the fact I’d trailed a module in the first year (L4). Unaware to me, I was told I was supposed to re-attempt the assignment I’d failed in the first year during this year, and given the fact I’d missed this year's reassessment point my academic studies were to be terminated in accordance with Academic Conduct. This was unclear to me as no member of staff from said module contacted me to state I needed to do so, nor was I scheduled any lectures or seminars prior to the reassessment. Despite passing L5 and demonstrating being able to proceed to final year, my studies have been terminated due to missing the reassessment point for a first year module (which doesn’t actually contribute to my degree?). Acknowledging this is perhaps a result of my naivety and accepting some responsibility, do I have any grounds to appeal this decision? And is there anything I can do to resume my studies at final year without resitting the first year module? Even if it means transferring to a different university under mitigating circumstances. What are my options?
