URGENT : HELP !!! : Name Mismatch, the exam time is today.

HI ,
I have scheduled my Exam today (2021/04/01). My Candidate name is not matching with ID proof.
Candidate Name :KEN YANG
ID Proof Name : CHIEN KUO YANG
Candidate ID : AWS01993028
I have already raised the Customer Support request on:
https://support.aws.amazon.com/#/contacts/aws-training
CASE : 8172203211
Is there any method to Contact Support Services ASAP?
If AWS support not response or fix my name before 18:00, then I will not able to take the exam, and this schedule also not able to be re-scheduled....

Great thanks if any AWS people can help!!
