Is this serious enough to complain about mistreatment and neglect?

Talk to your university student support team to have your problems recorded.
Talk to your student union about the process for resolving this at your university.
Talk to your faculty/department academic office and/or student records/registry team to understand what the university regulations say about your situation and your options.
Create a proper timeline of events with screenshots/dates/emails etc so that you can explain the situation clearly.

Thank you!

I have an appointment with Student Support tomorrow so I will find out what can be done.

Unfortunately there is nothing about situation like this in the Academic Regulations since I did not missed the official deadline. That’s why I am wondering if this lecturer is allowed to punish me in such way as this will mean I will not be able graduate.

Hi!
Currently in my third year of uni and considering dropping out, 4 weeks before my final submission.
It will be a long one so brace yourselves.
The level of neglect I experienced in my final year is beyond comprehension (not showing up for inductions, being always late, NEVER providing feedback even when they promise, not responding for even 4 months - yes, all of this was reported by several students, including me, within department and to multiple lecturers but nothing has been done). I am doing 2 advanced projects instead of a dissertation. Both of my supervisors basically were no help, nicely said. One of them is also my personal tutor, other one also a lecturer in my language module. I would ask my PT for an advice but as you can imagine, they are unresponsive. But onto the situation, I missed a “deadline”. Actually, this was not a real deadline and it wasn’t a coursework, but a part of it. It was a task that I had to attempt second time (first attempt in October) in order to see how much I improved in a language. The task is a part of my Language Portfolio that is 60% of a module grade and is not due for another 3 weeks. So, the task is a Microsoft Forms multiple options listening assignment that does not involve a lecturer to mark it as it gives the answers at the end automatically. Basically what happened, I missed the second attempt and the link to the assignment expired. I emailed the lecturer asap, when I found out I missed it (by 6 days). Obviously, they did not respond until I saw them available on Teams and resent the email content there, it was literally a small essay. I apologised, admitted it was my fault for not being careful, explained that I struggle massively and begged for help. The answer I got was 1 sentence, no hello or goodbye, nothing besides saying “shame” and that they need to think if they will provide me with the link. To add, all students can attempt this task multiple times but they need to ask for a new link. So I feel like they do make me wait for their decision as a sort of punishment because they probably found out that I reported about them neglecting me. Now I can’t complete my coursework because they basically refusing sending me a link to the task.
I never ever missed a deadline (real or not), never applied for mitigation circumstances, never asked for help. But as someone who struggles with anxiety and is taking medication for it I can’t take it anymore. My partner, seriously worried for my wellbeing as I completely broke down, called Student Support informing them what happened and they are expecting me to speak to them about the situation. As I was left to myself by all lectures and my PT, I came here to ask for an advice. I know I messed up but I did not miss my REAL deadline so do they have a right to block me from completing my coursework by doing so? Has anyone been in a similar situation? Please, I need some advice because I’m going crazy.
