Hello,

It would be much better if you could mention the exam you are talking about.

But don’t worry this happens most often.

So what you can do is send mail to the officials of the exam conducting body and tell them about the problem you faced.

You can find the contact details in their official website.

They will definitely help by giving you a solution.

Mostly they will ask you to bring your new certificate during the counselling session.

All the Best
