All India Institute Of Medical Science [AIIMS] — Payment not yet updated in the profile

I have done the payment through net banking for INI CET MDS registration, but it is not yet updated in my profile. The transaction was successful and the amount was deducted from my account. I have also tried to do another payment after waiting for 24hrs, but was not successful as it shows "A payment has already been initiated for the same reference number". I am not able to continue with my final registration for the selection of examination centres. Kindly look into this matter.
