Bank Of Baroda — transaction failure but amount debited

I was paying my semester tuition fees through an SBI portal, amount 30, 700/- Rs.
During the payment time, I chose to pay through Bank of Baroda debit card option and when I was paying I lost internet connection and transaction failed but later I got a message saying amount debited.
But I didn't receive any message saying fees successfully payed from SBI .
Please help me out with this. The amount is huge.
