Guru Nanak Dev University — Delay in refund of fees

I had applied to both GNDU main campus, Amritsar and regional campus, Jalandhar for admission in B.Tech CSE course. The admission process for regional campus started earlier and they gave me seat in CSE and I paid fees and everything was done. But later I was admitted to CSE course at main campus after attending classes for 7 days at regional campus. And I inquired if they would transfer my fees from the regional campus to the main campus but they said they won't. So I paid fees for main campus also and immediately sent application to CANCEL MY ADMISSION AT REGIONAL CAMPUS, JALANDHAR wanting for refund on the fees paid.
They asked me for some documents on the same day and till date I've asked many time about the status of my refund but they won't revert me back.
They also said they will deduct ATLEAST 40% of my fees for attending classes.
But in light of COVID-19 pandemic, the Ministry of Education, India had ruled that and I quote, "To avoid financial hardship being faced by the parents due to lockdown and related factors, a full refund of fees will be made on account of all cancellation of admissions/ migration of students, up to November 30, 2020, for this very session as a special case”.

Even if we ignore the pandemic situation, the UGC rules say that if cancellation of admission is notified within 10 days of commencement of the course, the deduction eligible on fees is ATMOST 20%.

Also, the UGC guidelines quote that, "Fees shall be refunded by all Higher Education Institutions to an eligible student within fifteen days from the date of receiving a written application from him/her in this regard."

And today it's the 15th day since I requested for refund and completed all the other formalities but haven't heard back from them and haven't got a single penny back. So all in all they're deducting my fees wrongfully and not even responding back regarding the matter and I'm just getting worried and I would be eternally grateful if you could help me in this matter.
