ICICI Bank — account debited order not placed - on easy pay

Address:	700124
Website:	dled.nios.ac.in

While making a payment of rs. 4510.00 for TEACHER REGISTRATION at http://dled.nios.ac.in/, i opted net banking payment from my IDBI on icici eazypay, however, while my account was debited, i received a failed transaction page of citrus. I checked my account and it was debited for rs. 4510 immediately. I contacted citrus, they said to contact icici, to which icici bank (Eazy pay) said since i did not have an account with them, they can't do anything about it.
I called citrus back, and they said they are just payment partner and they also can't do a thing about it.
I am stuck, and left in a deadlock situation where my money is lost forever. This is kind of agony i am going through. I have attached failed transaction page of citrus and have provided transaction details below. Please help me out to settle this issue.
