Like John said But also I will go one step further and say....go to their support help site and log a ticket
I would certainly log a ticket with the Oracle Certification Support team, provide as much detail as possible including the Oracle testing ID, the incident number and any info on date, time and location of the test. Let them know that Pearson VUE has closed the ticket and that you'd like to escalate the issue.
It is very unlikely that your answers were not recorded, but we can certainly take another look a the test to see if there are no recorded responses to the first 1/4 or 1/2 of your test. That would be the indicator that your responses were affected by the test center issue.

Thank you for your suggestion.
I would immediately retake the exam if I had confidence in Pearson VuE services but I want to clarify this issue.
If there were no technical problems I would have no doubt, but the the way Person VUE responded to me has only strengthened them and I was very annoyed.
If they were safe of the operation of the test application they would answer me immediately and accurately. They are used to receiving many complaints, because many technical issues occur during the tests. They know that candidates need to pass the exam as soon as possible and they cannot wait for long response times. They are not interested in the quality of the service.
Thank you for you suggestion! Maybe I chose an incorrect context. But I found here similar posts. In fact I had some doubts, but, searching in the web I found many posts that reinforced them.
