Dear aspirant,

no need to panic, the exam authorities have built their sevice for moments similar to these, as this is not a very uncommon issue. Please go to the exam page that you are talking about, you`ll find a CONTACT tab. There you`ll find either a phone number or an email id or generally both. Try reaching out to the authorities along with your papers in hand. It`s an easy systematic procedure.

Hope it helps.

Good luck!
