Delhi University — refund about fee

I took admission in stgb khalsa in second cut off in bcom hons. But then canceled it and took admission in the same course in ramjas. Then when finally dujat result came out and i get admitted into sscbs, i withdrew my adm. From ramjas. The difference between the fee paid initially in khalsa and sscbs fee is 11000 approx and this is not a small amount for a middle class indian family to ignore. The website said that the extra amount will be shown in wallet and then will be refunded after cu adm. Process ends. However the adm. Process ended and i am yet here waiting for my refund and on the top that there is no so called wallet section in my du account.
