Hi Aspirant,

First of all dont panic, because it might affect your preparation. Now first of all from the website find the helpline number or mail id. Now explain your mistake them over the call or in mail and provide sufficient proofs, so that they can understand your issue. After seeing all the facts they will guide you. It wont affect to your process, because you havent done anything wrong intentionally.

Hope this will helpful to clear your dilemma.
