Dear sir, i had applied for undergraduate admission in Delhi university and got admission in Ramanujan college and paid fee of Rs.12, 240 .
On second cut off, i withdrew my admission from Ramanujan college and took admission in Sri Aurobindo college whose fee was Rs.5, 880/- .
as per Delhi university's fee transfer system, my payment of Rs.12, 240/- was transferred to Sri Aurobindo college and the balance amount of Rs.6, 360 was shown as credit balance on my du id .e.i, [protected]@gmail.com.
Now on the third cut off, i change to P.G.D.A.V college and its fee is Rs.12, 280/- but only amount of Rs.5, 880/- was transferred to the college .so where did the credit balance of Rs.6, 360 went ?
is it in the refund process or what ?
Now i had to pay the balance fee of Rs.6, 400/- for P.G.D.A.V college again.
please let know about the credit balance of Rs.6, 360/-??
