Christ University — Application amount debited but status shows its incomplete

I was filling up my BCom application yesterday night and when I tried to pay for it . The payment failed at bill desk and the application stood incomplete. I tried thrice and it still failed. Today I got debited for 1000/-RS in total( ie twice for the same application) yet my application is still incomplete. I?m not able to upload screenshots in this report.kindly offer me a refund of a thousand rupees as I got debited for nothing here. I don?t want any applications currently
