All India Institute Of Medical Science [AIIMS] — payment fault

For the application of mbbs, aiims, i have successfully completed the 1 st step. I later proceeded into the 2nd step and made the payment. The amount has been deducted from the account but still the application form says the payment has not been made. I have patiently waited for hours hoping it to be resolved but still there is no success. The examination centers are quickly filling up.
Help me out please.
