Delhi University — I want to cancel my registration

Address:	New Delhi, Delhi
Website:	du.ac.in

I want to cancel my du registration as i have already paid without attaching my self attested class 12 marksheet. I want to know if my fee will get refunded and can i apply for a new registration after the refund.
I would really like to hear this from you as soon as possible. Please answer to my query because my candidature may get cancelled and i may not be able to apply again
