Articleship registration

Hi My name is Rajdeep.

I am In CA Final.

I had paid my articleship registration fees at the time of my IPCC Registration By Rs.12000 DD(Rs.9000 For IPCC+Rs.1000 For ATC + Rs.2000 For articleship registration).

Now in Final,I was Just Required to pay the final Registration Fees whis is Rs.10000 and the same i Paid.

Now,I received the letter From The Institute That The Balance Amount Is not Received Though They Sent The Books of Final.

That Means That My Articleship Registration Fees I Have to Pay Again.

What do I do?

I Also Checked My Articlleship Registration Status On ICAI.ORG Site But It is not registered.

I am Not Having any Proof of My Articleship Registration Fees.
