I reported the issue to the CELPIP test center within 24 hours, but my complaint was denied and I was left without any resolution. What can I do now?

I took my CELPIP test on September 5, but there were continuous disturbances caused by staff talking near the exam room door. This repeatedly distracted me, and I found myself looking toward the noise several times, causing me to miss important parts of the exam.

I reported the issue within 24 hours of the test, but I was told that staff are allowed to talk near the door. I feel this is unfair because the noise significantly affected my concentration and performance during the exam.

Could you please advise me on what I can do now and whether there is any way to have my complaint properly reviewed?
