Jipmer — regarding exam fee payment refund

Sir/mam,

I had done payment for jipmer mbbs exam 2018 form for my brother through sbi net banking. I had done payment twice (1513+1513) on 24/03/18, both time money has been deducted from my account and payment was successful, after making payment while it will redirect to jibmer site some "site cant be reached error" shown, and in exam form still its showing payment is not done. I request for refund.
So please help me with this matter.
