Gauhati University — Payment deducted and not refund

I'm a student of Arya Vidyapeeth College. With due respect and humble submission i would like to state that the B.A (honours)CBCS 2th semester examination form was filled up by me but unfortunately still my payment has not shown yet, but rs.680 was deducted from my bank account.And so I have done the payment 2nd time and it was successfully done. But the earlier money deducted from my bank account is not refund yet. And sir i would like to ask your help to check on my issue.

Thanking you.
