Am a student of M.A 2020 batch geography department Sonapur College under gauhati university. With due respect and humble submission I would like to state that 29th convocation registration online form was filled up by me but when I made the payment it showed "Payment Failed" and so I made the payment second time but again it showed "Payment Failed".So a total of Rs.5060 was deducted from my bank account.Although when i recheck my payment status was Successful and I could download my Payment Receipt.But an extra Rs.2530 that was deducted from my bank account I couldn't get it back. I would like to ask your help to check on my issue.
