Hey

There are 2or 3 possibility

One is; it will get cancelled and your money will get reflect back in your account.

Case 2 transaction may be done after some time.so check the status after some time.

Case 3 : money will deduct from your account and form filling also not done .So in this case you should talk to the customer care and concern for further proceedings.( Rare chance for the 3rd case)

Good luck.
