Good day vivek,
Your question is not related this forum. You should contact the company you took the exam at.
I searched online using google and I think that this the contact of ONVue
https://home.pearsonvue.com/Contact-Us.aspx
In the forums here you can come with technical questions mostly. This include a question from the exam if you did not succeed to solve and want so guideline
I hope that this help abit
good luck with your exam
