Looking for advice regarding how I should proceed with a dispute I’m having with ETS over a recent (attempted) GRE exam.

Here’s the situation:

I joined my at home test on time, having completed the equipment test check in prior, and was told in my proctor evaluation that my laptop camera was blurry (working, just of poor quality), and that I would have to use a different laptop in order to proceed, giving me no other option, even though my second camera was also connected and of high-quality video. This was unexpected as I've attached a screenshot of the camera requirements for the at home test listed on the ETS website and it never mentions camera quality, so I would have had no way of knowing this would be an issue.

I had obtained another laptop from a friend 10-15 minutes later and rejoined the test where I had various technical issues and could not join, even after following the advice of my proctors to edit computer settings and even restart my laptop.…
