AIIMS — fee payment issue

While applying for aiims (Ug), i came across a problem regarding fee payment. I had done transaction through master card, it was showing "your transaction is being initiated" but my dashboard showed that fees was unpaid but i recieed a message from the bank that payment was done. Finally i paid fees by some other means. But now the amount deducted through master card is not refunded. Kindly look into this matter
