One97 Communications — articleship registration fees to icai credited to one97 communication

Respected sir,
I have paid my articleship registration fees of rs 2000 twice which was 1st credited to icai on 22nd july but the registration wasn't completed so i paid again on 28th july and it was credited to one97 communication ltd. So i want a refund of rs 2000 which is gone mistakenly to one97 communication ltd.
