Unable to perform Exam AWS Certification Exam due to Last Name

Hi,Amazon Team

While giving the exam today morning at 10:45 AM IST of AWS Certification of Dev-ops Professional (DOP-C02). I was giving the exam from Pearson Vue. I used my passport as my identification proof on which my firstname is Hemachandiran and last name is Giri And on my AWS profile my first name is Hemachandiran and last name is G ( My Initial)

Before Exam even I'm not able to edit any of my personal information at AWS profile.

The details of the Exam which I was proceeding today morning

Exam: DOP-C02 - AWS Certified DEV-OPS Professional - English Candidate: Hemachandiran G (as per AWS profile) Candidate ID: AWS01961504 Registration ID: 468610356 Email-id: hemachandiran1102@hotmail.com ( I register exam through this mail ID only everytime)

I have cleared AWS Solution Architect Associate with the same as a Identification proof so why is it causing issue this time.

I also mailed many time to AWS Support to assist but no response , so I was not able to perform exam.

I have Case ID which Pearson Procter created Case Id- 10816988

I request you to re-schedule the exam or initiate a refund so that I could proceed further.

As the Pearson Team told if you were able to give exam earlier with same ID , AWS can reshedule or refund for the Inconvenience caused you today during the exam. And I was waiting for AWS Support from last 10 hrs

Kindly assist me. AND please tell me if some certificate required from last certifications.

Thanks & Regards, G Hemachandiran
