Delhi University — fee refund information and status

Sir, i took admission in sgtb khalsa college right after the first cut off this year i. E. 29 june. But cancelled my admission on 8 july 2019 online. The cancellation fees had been imposed but i'm yet to know any information about my fee refund. They don't have any of our bank details, in what form and under which duration our fees will be refunded?
Everything was so organized just until the fees was about to be paid, yet there's nothing but silence when we want our money back. No helpline service works, no mails replied, its really contemptible on the part of such a huge and prestigious university.
