Bill Junction Dot Com — Amount debited but not credited into receiver's account

On 10th July I made the payment of Rs. 2, 20, 000 for my cousin's fess for the admission in Christ University, Bangalore. I made the payment using the link provided by the college "http://app.christuniversity.in". The amount was debited from my account but wasn't received by the college. When I contacted the bank they provided me the merchant name "Bill junction dot com". Request you to raise my refund as I again did the IMPS to the college.
