All India Institute Of Medical Science [AIIMS] — Ini cet 2021 july registration issue

I have paid thrice and the payment has gone through from my side aswell yet i cannot proceed further. I hv been calling the helpline numbers since 2 days to no avail. Now it says the registration is stopped!? Kindly help and address the issue .
i request Aiims ini cet authorities to resolve the issue and extend the registration as the problem exists on their end.
Also plz do refund our extra amount but most importantly resolve the registration issue as our year worth of time is at stake.
