Dear Fathima, AIIMS authorities haven't announced any resolutions for this issues regarding the final registration process. What you tried is what many tried and it worked for few. The rest are still trying the same procedure. However since yesterday or the the day since this final registration began, totad more no. of candidates were able to complete the registration process. We understand that it is nerve cracking but all we can do right now is to be patient and keep trying. It will take time but eventually you will be able to complete the process. Your transaction details that you have received from the Bank regarding the payment is a proof that the amount was debited from your account. It needs to be updated on their servers. So dont panic ans things will work out.
