Upgrad — Refund Request because of the fault of Swapnamita-Student Mentor Masters September Batch

I was enrolled for PG Diploma +Masters in Data Science course. In September 2020 my PGD got finished. Then the Masters was about to start.
But due to my father's spine injury, I took the deferral for Masters September Batch to December batch. At that time my Student mentor was Swapnamita. I informed her all about my situation and then she told me to send the required Medical Certificates.
I sent all of it and she said that your deferral request is accepted and you are deferred to December Batch.

Then the December Batch started, In my learn.upgrad.com dashboard I can also see the December batch details. So I was also satisfied that my deferral is approved.

Then when the time came for getting the credentials from LJMU. I got no emails from LJMU. Then I contacted Sneha (Student mentor of December batch) She told that because of Swapnamita Mistake the details were not passed on to her. And now she is telling me to get deferred to March Batch or any next batch.

I told her that I am not in the mood of taking another deferral. I want a a full refund of my course fees. It is that simple because you have no right to force me to another month deferral. She is forcing me to take the deferral. What kind of behavior is this? She even asked for the reasons why you can't go to the march batch? Who is she to ask that? Though I told her everything, all my reasons because of which I cannot proceed with the deferral anymore. Then She alleged "ARE YOU TAKING THIS AS AN OPPORTUNITY FOR A REFUND "

Seriously??

I felt so humiliated at that time.
What kind of behavior is this? I am a middle-class student who just got a JOB as an intern with my own hard work(not from upgrad career) And they are offering me the big project, I had planned everything according to that then how can I accept the deferral and move on to some another month.
I also dropped a mail-in Student Support and even their Supervisors but
they told me to go for deferral to another month.

How fair is that?
They are just saying this is because of Swapnamita and forcing me to take deferral.
If the fault is from Upgrad's End then why I am going to suffer.
They have given money to LJMU institution thats why they are forcing me for deferral and dont want to bear the loss themselves.

This is not fair in any means
I dont want to take deferral I want my money back.
