Proctor misconception revoked exam - Pathetic service by Pearson?

Unacceptable experience with Pearson.

I have scheduled AWS Cloud Practitioner exam on 18th December 2 PM, Here are the issues I faced:

1. I ran system at 1:15 eveything was OK during the system test
2. 1:45 PM agent chat me that he cant hear me and put me back to the queue
3. 2:15 PM another agent said the same thing and put me back the queue
4. after 30 minutes some agent allowed to the exam
5. While I was writing the exam, some proctor gave me a warning that I should not speak loud I said ACK
6. Immediately she has a misconception of thirdparty entered into the room left side webcam, in reality that's a mirror reflection at my back
7. revoked the exam immediately and she has not given me option to explain as well and note down the customer care - Case ID : 07419031
8. I contacted Pearson Customer care, they were not able to help me and hung up
9. Sent an email to Pearson Customer care, no response yet
10. After few calls, I insisted them to investigate, they came back to me saying exam was revoked correctly
11. Spoke to senior supervisor Bryan, he suggested me to contact AWS, & he doesn't know how to contact AWS ( No information provided ) just said contact AWS
12. Now, I explored myself to contact you about this issue.
13. Please get the investigation done, and share me the proof of picture that third party entered into my room.
14. Based on the pictures shared, I will decide to go legally or not.
15. Pearson is a pathetic service I have ever seen
