Ggsipu — counselling fees deducted twice

Sir when i am filling the counelling money which is ₹1000 via debit card. But after completion of all the steps and deducation of fee from my account the message popped on the college website reading -"error occured and try again later".
Hence i did not recieve any payment reciept but the amount has been deduacted from my bank account.
I tried contacting helpdesk of the university but as usual the line was either engaged or not reachable i even mailed them but no reply from their end.
I contacted my bank and they said that the merchant bank has accepted the payment.
I have no clue what to do next.
Kindly look into the matter and oblige.
